Afternoon Sermon: What Is Sanctification?, Baptist Catechism 38, Ephesians 4:17–32

Baptist Catechism 38

Q. 38. What is sanctification?

A. Sanctification is the work of God’s free grace whereby we are renewed in the whole man after the image of God, and are enabled more and more to die unto sin, and live unto righteousness. (2 Thess. 2:13; Eph. 4:23,24; Rom. 6:11)

Scripture Reading: Ephesians 4:17–32

“Now this I say and testify in the Lord, that you must no longer walk as the Gentiles do, in the futility of their minds. They are darkened in their understanding, alienated from the life of God because of the ignorance that is in them, due to their hardness of heart. They have become callous and have given themselves up to sensuality, greedy to practice every kind of impurity. But that is not the way you learned Christ!— assuming that you have heard about him and were taught in him, as the truth is in Jesus, to put off your old self, which belongs to your former manner of life and is corrupt through deceitful desires, and to be renewed in the spirit of your minds, and to put on the new self, created after the likeness of God in true righteousness and holiness. Therefore, having put away falsehood, let each one of you speak the truth with his neighbor, for we are members one of another. Be angry and do not sin; do not let the sun go down on your anger, and give no opportunity to the devil. Let the thief no longer steal, but rather let him labor, doing honest work with his own hands, so that he may have something to share with anyone in need. Let no corrupting talk come out of your mouths, but only such as is good for building up, as fits the occasion, that it may give grace to those who hear. And do not grieve the Holy Spirit of God, by whom you were sealed for the day of redemption. Let all bitterness and wrath and anger and clamor and slander be put away from you, along with all malice. Be kind to one another, tenderhearted, forgiving one another, as God in Christ forgave you.” (Ephesians 4:17–32, ESV)

    • The Catechism Explained
    • “Sanctification is the work…”
      • A work is a process.  
    • “…of God’s free grace…”
      • “But we ought always to give thanks to God for you, brothers beloved by the Lord, because God chose you as the firstfruits to be saved, through sanctification by the Spirit and belief in the truth.” (2 Thessalonians 2:13, ESV)

      • “They have become callous and have given themselves up to sensuality, greedy to practice every kind of impurity. But that is not the way you learned Christ!— assuming that you have heard about him and were taught in him, as the truth is in Jesus, to put off your old self, which belongs to your former manner of life and is corrupt through deceitful desires, and to be renewed in the spirit of your minds, and to put on the new self, created after the likeness of God in true righteousness and holiness.” (Ephesians 4:19–24, ESV)
    • “And are enabled more and more to die unto sin, and live unto righteousness.”

  2. Application
    • Notice that sanctification is called the “work” instead of the “act” of God’s free grace. Why?
    • Are you sanctified?
    • Are you being sanctified?
