Old Testament Reading: Genesis 10:1-2, 5-6, 20-22, 31-32

“These are the generations of the sons of Noah, Shem, Ham, and Japheth. Sons were born to them after the flood. The sons of Japheth: Gomer, Magog, Madai, Javan, Tubal, Meshech, and Tiras… [Verse 5] From these the coastland peoples spread in their lands, each with his own language, by their clans, in their nations. [Verse 6] The sons of Ham: Cush, Egypt, Put, and Canaan… [Verse 20] These are the sons of Ham, by their clans, their languages, their lands, and their nations. [Verse 21] To Shem also, the father of all the children of Eber, the elder brother of Japheth, children were born. The sons of Shem: Elam, Asshur, Arpachshad, Lud, and Aram… [Verse 31] These are the sons of Shem, by their clans, their languages, their lands, and their nations. [Verse 32] These are the clans of the sons of Noah, according to their genealogies, in their nations, and from these the nations spread abroad on the earth after the flood.” (Genesis 10:31–32, ESV)

New Testament Reading: Luke 10:1-20

“After this the Lord appointed seventy-two others and sent them on ahead of him, two by two, into every town and place where he himself was about to go. And he said to them, ‘The harvest is plentiful, but the laborers are few. Therefore pray earnestly to the Lord of the harvest to send out laborers into his harvest. Go your way; behold, I am sending you out as lambs in the midst of wolves. Carry no moneybag, no knapsack, no sandals, and greet no one on the road. Whatever house you enter, first say, ‘Peace be to this house!’ And if a son of peace is there, your peace will rest upon him. But if not, it will return to you. And remain in the same house, eating and drinking what they provide, for the laborer deserves his wages. Do not go from house to house. Whenever you enter a town and they receive you, eat what is set before you. Heal the sick in it and say to them, ‘The kingdom of God has come near to you.’ But whenever you enter a town and they do not receive you, go into its streets and say, ‘Even the dust of your town that clings to our feet we wipe off against you. Nevertheless know this, that the kingdom of God has come near.’ I tell you, it will be more bearable on that day for Sodom than for that town. ‘Woe to you, Chorazin [Χοραζίν]! Woe to you, Bethsaida [Βηθσαϊδά] ! For if the mighty works done in you had been done in Tyre and Sidon, they would have repented long ago, sitting in sackcloth and ashes. But it will be more bearable in the judgment for Tyre and Sidon than for you. And you, Capernaum [Καπερναούμ], will you be exalted to heaven? You shall be brought down to Hades. ‘The one who hears you hears me, and the one who rejects you rejects me, and the one who rejects me rejects him who sent me.’ The seventy-two returned with joy, saying, ‘Lord, even the demons are subject to us in your name!’ And he said to them, ‘I saw Satan fall like lightning from heaven. Behold, I have given you authority to tread on serpents and scorpions, and over all the power of the enemy, and nothing shall hurt you. Nevertheless, do not rejoice in this, that the spirits are subject to you, but rejoice that your names are written in heaven.’” (Luke 10:1–20, ESV)

Introduction

Here in Luke 10:1-20, we find a very similar story to the one told in Luke 9:1-6. In Luke 9, we learned about Jesus sending out his 12 Apostles “to proclaim the kingdom of God and to heal” (Luke 9:2, ESV). Here in Luke 10, Jesus sends out a larger group of disciples with the authority to heal, cast out demons, and preach the gospel of the kingdom.  

Some manuscripts say the number sent out was 70. Others say the number was 72. The ESV goes with the number 72. If you are reading from the AV, the KJV, NKJV, or NASB, you’ll see that they follow those manuscripts that list the number at 70. I should take this opportunity to remind you that we are reading English translations of copies of the Scriptures originally written in Hebrew and Greek. In the ancient manuscripts, we do find variations like this. Again, some say that 70 disciples were sent out, and some say 72. The reason for the discrepancy probably has something to do with the Genesis 10 passage that I read a moment ago, and the Numbers 11:16-30 passage that I read two Sundays ago as our Old Testament reading. 

In Genesis 10 we find a list of the nations of the earth that descended from Noah and his sons, Shem Ham, and Japhet. The Hebrew texts list 70 nations, but the Septuagint, which is a very old Greek translation of the Old Testament – a translation used widely in the days of Christ – lists 72 nations descended from Noah. 

If you remember, Numbers 11:16-30 tells the story of the appointment of 70 elders to govern Israel alongside Moses. The 70 elders assembled at the Tabernacle and the Spirit fell upon them, enabling them to prophesy temporarily. But the story goes on to tell of two men who did not assemble at the Tabernacle upon whom the Spirit also fell, and they prophesied. This bothered Joshua, remember? He wished to command them to stop, but Moses forbade him. So the question is, were there 70 elders placed over Israel, or 72? 

I will not pretend to have the answers, brothers and sisters. Here I am drawing your attention to the discrepancy in the manuscripts and wish to point to the probable cause. Were there 70 or 72 nations listed in Genesis 10? Were there 70 or 72 elders appointed to rule in support of Moses? I’m not entirely sure. What seems clear to me is that an attempt was made by some scribe living somewhere at some point in time to reconcile these accounts, and I believe this is the important thing to notice. The Biblical accounts of the 70/72 nations that descended from Noah and his sons, the appointment of 70/72 elders to rule over Israel, and Jesus’ sending out of 70/72 disciples with the authority to heal, cast out demons, and preach the gospel of the kingdom, are meant to be connected. Add to this Exodus 1:5 which reveals the number of the descendants of Abraham, Issac, and Jacob that went down into Egypt, saying,  “All the descendants of Jacob were seventy persons; Joseph was already in Egypt” (Exodus 1:5, ESV). My gut tells me the number in Luke 10 ought to be 70, but I don’t want to focus on that this morning. In a way, it doesn’t matter. 

The Meaning Of The 70/72

The question is, why did Jesus send 70/72 disciples out? You say, to further Christ’s kingdom! To do the work that Christ commanded them to do! Yes, we will come to that. But here I am asking, what is the significance or meaning of their number?

I suppose it would help us to first remember the significance of the number 12. Christ appointed 12 Apostles and this number corresponds to the number of tribes in Old Covenant Israel. The 12 Apostles functioned as the foundation and source of the New Covenant Isarel of God, therefore. A new, or perhaps we should say, renewed, Israel would be brought into existence through them and established upon their word. 

And there is a similar meaning attached to the number 70/72. 70/72 nations descended from the sons of Noah. 70 descendents of Abraham, Isaac, and Jacob entered Egypt. God’s purpose was to multiply them greatly there, to redeem them from bondage, to make them into a great nation, and to give them a land of their own. Why? To bring the Messiah into the world through them, and to save sinners from all nations through him. The 70/72 elders that were appointed to govern Israel alongside Moses (see Exodus 24 and Numbers 11) correspond in number to the nations listed in Genesis 10. This was no accident but was a reminder of the purpose for which God has set Abraham and Israel apart originally, namely, to bless all of the nations of the earth through them, that is to say, through the Messiah, the Son of Abraham, that would be brought into the world through them (see Genesis 12:1-3). When Jesus sent out a group of disciples numbering 70/72, it was to remind us of this history. Furthermore, it was to communicate this message – Christ came to establish the Kingdom of God, a New Covenant, and to bring a new Israel into existence. This kingdom, Covenant, and Israel would include sinners, redeemed by the blood of Christ, from every tongue, tribe, and nation on earth. These will be the members of the new humanity that will one day fill the new heavens and earth that Christ has earned. That is the story told by the number 70/72. It is a number filled with Biblical significance. When Christ sent out the 70/72 it communicated his intention to purify Israel under the New Covenant and to graft people from every tongue, tribe, and nation – the peoples that descended from Noah –  into her. 

*****

The Mission Of The 70/72

So, we have considered the significance or meaning of the number of disciples sent out. What was their mission? Answer: These were sent out to proclaim that the kingdom of God was at hand. Look at verses 9-11. There the 70/72 are commanded to go from town to town and to “Heal the sick in it and say to them, ‘The kingdom of God has come near to you.’ But whenever you enter a town and they do not receive you, go into its streets and say, ‘Even the dust of your town that clings to our feet we wipe off against you. Nevertheless know this, that the kingdom of God has come near’” (Luke 10:9–11, ESV). These disciples of Jesus were to go forth and proclaim the gospel of the kingdom of God.

We have answered the question, what is the kingdom of God many times now in our study through Luke’s Gospel. I’ll remind you, briefly, that God is King over all things. He is the sovereign one. He is Lord Most High. But ever since Adam sinned, there have been two kingdoms in this world. The kingdom of darkness and death is ruled by Satan, the usurper. The kingdom of light and life is ruled by Christ, the Second Adam, the eternal Son of God incarnate. Christ, his kingdom, and his Covenant were promised even to Adam and Eve. That promise was carried along and advanced in the covenants that God made with Abraham, Israel (in the days of Moses), and King David. But the kingdom of God, over which Christ rules, and the Covenant of Grace that he mediates, did not come into the world until his work of redemption was accomplished. Before Christ died and rose again, the kingdom of God and the Covenant of grace were present in the world in the form of promise. Salvation came to all who trust in the promises of God. But the kingdom of God (of which Christ is King) and the Covenant of Grace (of which Christ is the only mediator) were not inaugurated or formally begun until Jesus’ life, death, resurrection, and ascension to the Father’s right hand. This is why we have heard John the Baptist, Jesus, and his disciples proclaiming the nearness of the kingdom of God. In saying that it was “near” or “at hand” they meant that the kingdom was not yet present. Yes, it had been offered to Adam in the Covenant of Works before his fall into sin. The kingdom of God was also promised to Adam in that first articulation of the gospel (see Genesis 3:15). As I have said, this promise was carried along, magnified, and clarified in the covenants made with Abraham, Israel, and David. In fact, the kingdom of God that was to come was beautifully pictured in Old Covenant Israel, especially in the kingship of David, but never was present with power. The kingdom of God was said to be “near” or “at hand” when Jesus walked the earth. Why?

One, because Jesus is the only King of God’s kingdom. He is the son who was promised to King David. He is the King who rules over God’s kingdom forever and ever. 

Two, it was King Jesus who delivered and redeemed God’s elect from every age from bondage to Satan, sin, and the fear of death. This great work of redemption was promised beforehand (see Genesis 3:15, for example). This work of redemption was also pictured beforehand (in the Exodus, for example). But the redemption was not accomplished until Christ died, rose again, and ascended.  

Three, when I say that King Jesus delivered and redeemed God’s elect you should know that he did so by delivering a fatal blow to the head of Satan, the usurper king. In other words, the establishment of God’s kingdom involved the overthrow of Satan’s kingdom. This defeat of Satan and the overthrow of his kingdom was promised beforehand (see Genesis 3:15, for example). It was also pictured beforehand (think again of the Exodus, especially the Ten Plagues). But Satan was not struck upon the head – he was not bound or cast down so that his house might be plundered – until Jesus Christ dropped his wounded heal upon him at the cross. 

The kingdom of God was said to be “near” or “at hand” when Jesus walked the earth because he is the King of this eternal kingdom. He was about to win the victory over Satan through the suffering of the cross. He was about to pay for the sins of all who trusted in him, before, during, and after his life on earth, so that they might be forgiven. When he ascended into heaven he opened up the way to God for his people. When he ascended, he sat down upon his eternal throne. When he ascended, he sent forth the Holy Spirit to enliven, anoint, and empower all of his people – his elect from every tongue, tribe, and nation on earth. 

This was the mission given to these 70/72. They were to go from town to town proclaiming the nearness of the kingdom of God. The mission of the church today is similar. It differs only in perspective. We are to proclaim that the kingdom of God is here, that Christ is King, that he has won the victory, has entered into glory, and will one day return to judge his enemies, to acquit those united to him by faith, and to make all things new.     

Notice that these 70/72 were, like the 12 before them, given the power and authority to heal the sick (v. 9) and to cast out demons (vs. 17-19). They were enabled to perform these miraculous deeds as a sign that the message the proclaimed was true. The presence of the kingdom of God was declared and it was also demonstrated by these special emissaries of Jesus. The writer of Hebrews tells us that this was the purpose of these miracles. Listen to Hebrews 2:3-4: “how shall we escape if we neglect such a great salvation? It was declared at first by the Lord, and it was attested to us by those who heard, while God also bore witness by signs and wonders and various miracles and by gifts of the Holy Spirit distributed according to his will.” (Hebrews 2:3–4, ESV)

What was the mission given to the 70/72? They were sent out to preach the gospel of the kingdom of God. They were also to heal and to cast our demons as a demonstration of the fact that their message was true. And so they did. 

*****

The Method Of The 70/72

We have considered the meaning and mission of the 70/72. Let us now briefly consider their method. How did they go about accomplishing this mission that was given to them?

Firstly, they were to go ahead of Jesus to prepare the way for him. This is what verse 1 says. By the way, this is what we do whenever we proclaim the gospel of the kingdom. We prepare the way for Jesus. The gospel is the power of God for salvation, but no one will ever be saved unless Jesus comes to that person by the working of the Holy Spirit to give them life and the ability to believe. 

Secondly, these disciples of Jesus were sent out two by two. In this way, they functioned as credible witnesses. In this way, they supported and encouraged one another in the work. Brothers and sisters, it is good to go about the work that God has given us to do, not alone, but with other brothers and sisters in Christ. Do not walk alone, friends. The proverb of Ecclesiastes 4:12 is true! “And though a man might prevail against one who is alone, two will withstand him—a threefold cord is not quickly broken” (Ecclesiastes 4:12, ESV).

Thirdly, these disciples of Jesus were sent out having been exhorted to pray. Look at verse 2: “And [Jesus] said to them, “The harvest is plentiful, but the laborers are few. Therefore pray earnestly to the Lord of the harvest to send out laborers into his harvest” (Luke 10:2, ESV). The field is the world. The grains ripe for the picking are the elect of God. The laborers are ministers of the word of God. The Lord of the harvest is God. And God’s people are commanded to pray. More than this, we are commanded to pray earnestly, that is, with a sense of urgency and seriousness. Are you praying, dear brothers and sisters? Are you praying earnestly, especially for the success of the gospel in this land through the sending out of laborers into the harvest? 

Fourthly, Jesus sent his disciples out as lambs in the midst of wolves. That is what verse 3 says, “Go your way; behold, I am sending you out as lambs in the midst of wolves” (Luke 10:3, ESV). The  meaning is that Jesus’ disciples were sent into a situation where they would be very vulnerable, at least from a human perspective – they would need to trust the Lord, therefore. The wolves represent viscous men. Also, we can see that the disciples were to go out with no provisions. Christ instructed them to “Carry no moneybag, no knapsack, no sandals…” (Luke 10:4, ESV). They were to rely on the hospitality of strangers.  Brothers and sisters, this was a very unique mission that these disciples were sent on. Not every disciple of Jesus is called to go out like this. In fact, very few are. As you probably know, Jesus would send these same disciples out with different instructions later, saying, “But now let the one who has a moneybag take it, and likewise a knapsack. And let the one who has no sword sell his cloak and buy one” (Luke 22:36, ESV). Why did Christ command them to go out in such a vulnerable condition? No doubt, it was to teach them to trust. Dear brothers and sisters, we too must trust the Lord. We must walk by faith. When we feel vulnerable, as if sheep amongst wolves, we must turn to face the fear and anxiety and trust in God and in Christ to preserve us and to provide for our every need.

Fifthly, Jesus commanded that his disciples be undeterred in their work. This principle permeates verses 5 through 16. Look at verse 5: “Whatever house you enter, first say, ‘Peace be to this house!’ And if a son of peace is there, your peace will rest upon him. But if not, it will return to you” (Luke 10:5–6, ESV). Look now at verse 10: “But whenever you enter a town and they do not receive you, go into its streets and say, ‘Even the dust of your town that clings to our feet we wipe off against you. Nevertheless know this, that the kingdom of God has come near’” (Luke 10:10–12, ESV). The disciples of Jesu were not to be discouraged nor detoured by rejection. Some would receive their word; others would not. The disciples were to bless those who received them and their word. When rejected, they were to brush it off and warn of judgment.  

It is the day of judgment that Christ spoke of when he said, “I tell you, it will be more bearable on that day for Sodom than for that town” (Luke 10:12, ESV). He elaborates on this theme of judgment in verses 13 through 15, saying, “Woe to you, Chorazin [Χοραζίν]! Woe to you, Bethsaida [Βηθσαϊδά] ! For if the mighty works done in you had been done in Tyre and Sidon, they would have repented long ago, sitting in sackcloth and ashes. But it will be more bearable in the judgment for Tyre and Sidon than for you. And you, Capernaum [Καπερναούμ], will you be exalted to heaven? You shall be brought down to Hades.” These cities that Christ pronounced woes upon, were cities within Israel. They were cities where Christ and his disciples taught and performed signs and wonders. And yet, so many rejected him. So many from within these towns refused to repent and believe. Tyre and Sidon were Gentile cities known for their sin. Christ said, his mighty works had been done there, “they would have repented long ago, sitting in sackcloth and ashes.”  So, in this way, Christ rebukes Israel’s unbelief and signals his intention to work mightily amongst the Gentile nations.

In verse 16 we read the words of Christ to his disciples: “The one who hears you hears me, and the one who rejects you rejects me, and the one who rejects me rejects him who sent me” (Luke 10:16, ESV). I have said that Christ commanded that his disciples be undeterred in their work. By that I mean they were commanded to be faithful in their work. They were to preach the gospel of the kingdom and they were to brush off all rejection. After all, it was not they who were being rejected, but God and Christ. Furthermore, the disciples were to know for certain that some would receive their word, and to receive their word was to receive the word of Christ. All Christians must be undeterred in their proclamation of the gospel of Jesus Christ. You must not be afraid of rejection or discouraged by it when it comes. The saying is true, we must preach the gospel and leave the results to God. But this is an especially important lesson for ministers to learn. Ministers must be faithful to preach and teach Christ. Many will reject the word because they are dead in their sin and destined for judgment. Others will receive the word gladly. This is because God has shown grace to them. He predestined them in eternity to have life in Christ. He sent forth his word and Spirit. He enlightened their minds and made them willing and able to believe in Christ. When these hear the gospel, they hear the voice of Christ. This is God’s work. It is true, we must be resolved to preach and teach the word of God faithfully and leave the results to God.

*****

The Marvel Of The 70/72

We have considered the meaning, mission, and method of the 70/72. Finally, let us consider their marvel. To marvel is to be filled with wonder and astonishment, and that is what we see in verse 17. There we read, “The seventy-two returned with joy, saying, ‘Lord, even the demons are subject to us in your name!’” (Luke 10:17, ESV). They were astonished by this, and rightly so. 

Notice that Christ did not discourage them or seek to quench their enthusiasm. To the contrary, he encouraged them further, saying in verse 18, “I saw Satan fall like lightning from heaven. Behold, I have given you authority to tread on serpents and scorpions, and over all the power of the enemy, and nothing shall hurt you. Nevertheless, do not rejoice in this, that the spirits are subject to you, but rejoice that your names are written in heaven” (Luke 10:18–20, ESV).

There are three things to note about these verses. 

Firstly, Christ confirmed what these disciples had experienced. Satan and his kingdom were indeed being overthrown. The disciples had great success in casting out demons, but here Jesus opened their eyes to the reality of the much greater work he was doing. He did not only come to cast individual demons out of individual persons but to cast Satan himself out of heaven. This he was doing, and this he would do in his life, death, resurrection, and ascension. 

What does it mean that Satan was cast out of heaven? We should remember that before Christ accomplished our redemption, Satan was permitted to accuse God’s people in heaven. The book of Job makes this clear. Job 1:6 says, “Now there was a day when the sons of God came to present themselves before the LORD, and Satan also came among them…” (Job 1:6, ESV). And what did Satan do, except accuse Job? When Christ finished his work of redemption, Satan was cast down from heaven. The Son of God came down in the incarnation so that he might be exulted to the glory. And it was then that Satan, who had exulted himself in sinful pride and rebellion, was cast down, having been defeated by Christ the Lord. 

This casting down of Satan of which Christ speaks is depicted in the Book of Revelation 12:7-17. If you are accustomed to reading the Book of Revelation as if it were chronologically organized, you will not be able to appreciate this. But if you have learned to read the Book of Revelation as a serries of seven recapitulations, then you will be able to connect what is said by Jesus in Luke 10 with the picture of Revelation 12. It was at Christ’s first coming that Satan was cast from heaven. Listen to Revelation 12:10 where John says, “And I heard a loud voice in heaven, saying, ‘Now the salvation and the power and the kingdom of our God and the authority of his Christ have come…’” May I pause and ask you the question, when did that happen? Yes, at Christ’s first coming. I’ll start again in Revelation 12:10: “‘Now the salvation and the power and the kingdom of our God and the authority of his Christ have come, for the accuser of our brothers has been thrown down, who accuses them day and night before our God. And they have conquered him by the blood of the Lamb and by the word of their testimony, for they loved not their lives even unto death. Therefore, rejoice, O heavens and you who dwell in them! But woe to you, O earth and sea, for the devil has come down to you in great wrath, because he knows that his time is short!’” (Revelation 12:10–12, ESV).

Friends, Christ defeated Satan and his kingdom of darkness at his first coming. When Christ was exulted to his legitimate throne, Satan was cast down from his illegitimate throne, and he was bound so that he could not deceive the (70/72) nations any longer. This does not mean that he is not active. It means that he is cast down from heaven so that he can no longer accuse God’s people.  Why could he accuse before? Because Christ had not yet paid for the sins of those who trusted in him. By the way, this is why those who had faith prior to the accomplishment of our redemption resided in Abraham’s bosom, that upper portion of Sheol or Hades (Luke 16:23). It was a place of comfort but it was not heaven. It was because our salvation had not yet been accomplished – our sins not yet paid for – that the way to heaven was not yet opened up for them. And what did Satan say about God’s people alive on earth and those who were comforted in Sheol at the side of Abraham? They are guilty! This is unjust! You cannot comfort them! You cannot pass over their sins (see Romans 3:21-26)! They are mine! You must condemn them forever! But when Christ accomplished our salvation by his death, burial, and resurrection, he ascended. When he ascended, he cast Satan down. When he ascended, he set the captives of Sheol free and led them in the very presence of the glory of God Almighty. Do you remember the song that Mary the mother of Jesus sang when she visited Elizabeth? She gave praise to God saying, among other things, “he has brought down the mighty from their thrones and exalted those of humble estate…” (Luke 1:52, ESV). May I suggest to you that this bringing down of some and exulting of others is true in the angelic and spiritual world before it is true of us.  

The second observation I would like to make about Luke 10:17-20 is that he confirmed his disciples have authority over the enemy. Look at verse 19: “Behold, I have given you authority to tread on serpents and scorpions, and over all the power of the enemy, and nothing shall hurt you” (Luke 10:19, ESV). 

When Christ spoke of giving his followers the “authority to tread on serpents and scorpions” it should be clear to all that these creatures – serpents and scorpions – symbolize Satan and his demons. The end of verse 19 makes this clear, where Christ mentioned their authority “over all the power of the enemy.” Verse 20 also makes it clear that Christ is speaking of spiritual beings when he says, “Nevertheless, do not rejoice in this, that the spirits are subject to you…” In other words, Jesus is not here teaching that Christians cannot be hurt by litteral scorpions and snakes. You say, well what about the ending of Mark? And what about that story in  Acts 28 about the viper came out of the fire and bit Paul on the hand but he was not harmed? Yes, in that instant Paul was miraculously spared from a snake bite that would have typically resulted in death. it was a sign that his word was true. It was a miracle that demonstrated the power of the gospel that Paul proclaimed. And there was much symbolism in the miracle –  the viper that struck Paul from the hellish flames did him no harm to make it clear to all that Satan and the fires of hell would do no harm to Paul. Why? Because of Christ’s victory and Paul’s faith in him.   

When you read Jesus’ words to his disciples found at the very end of verse 19, “and nothing shall hurt you”, what do you think? Do you think to yourself, but many of these men were hurt badly? Some were even killed because they were followers of Jesus. Again, I’m afraid your thinking is too earthly. The truth is, nothing can hurt a true disciple of Jesus – not even death. Will the disciples of Jesus suffer and even die? Yes. But the sting has been removed. Satan and his demons – even death itself – cannot hurt the true follower of Christ because Christ has won the victory over sin, Satan, and death and has secured life eternal for all who are united to him by faith.   

Why would Christ need to say all of this all of this?  Why would he need to confirm the disciple’s authority over the evil one? Did Christ not just say that he saw Satan fall like lightning from heaven? Where did he fall to, except the earth? This is why Peter says, “Be sober-minded; be watchful. Your adversary the devil prowls around like a roaring lion, seeking someone to devour” (1 Peter 5:8, ESV). This is why, after describing the casting down of Satan, Revelation 12:12 says, “Therefore, rejoice, O heavens and you who dwell in them! But woe to you, O earth and sea, for the devil has come down to you in great wrath, because he knows that his time is short!” (Revelation 12:12, ESV). Indeed, it is true, that Satan is defeated, bound, and cast down, but he is very active. We must fight against him with the word of God and with much prayer. We must fight against him knowing that he can do us no harm. 

The third and final observation that I have about verses 17-20 is that Christ directs his disciple’s attention to what they should really be marveling and rejoicing over. Verse 20: “Nevertheless, do not rejoice in this, that the spirits are subject to you, but rejoice that your names are written in heaven” (Luke 10:20, ESV). It is wonderful to have authority over evil spirits. It is much better to know that you are destined for heaven. To have your name written in heaven means that you are already there on the basis of God’s decree. In heaven, there is a book of life (Philippians 4:3; Revelation 3:5, 13:8, 17:8, 20:12, 20:15, 21:27). It is a book written before the foundation of the world. Those whose names are in this book are the ones who will have faith in Christ. It will be these who will enjoy life in the glorious presence of God in new heavens and earth, by God’s grace. Of all of the things we might marvel and rejoice over, this is the greatest.
