Galatians 3:15-22

15 To give a human example, brothers even with a man-made covenant, no one annuls it or adds to it once it has been ratified. 16 Now the promises were made to Abraham and to his offspring. It does not say, “And to offsprings,” referring to many, but referring to one, “And to your offspring,” who is Christ. 17 This is what I mean: the law, which came 30 years afterward, does not annul a covenant previously ratified by God, so as to make the promise void. 18 For if the inheritance comes by the law, it no longer comes by promise; but God gave it to Abraham by a promise. 19 Why then the law? It was added because of transgressions, until the offspring should come to whom the promise had been made, and it was put in place through angels by an intermediary. 20 Now an intermediary implies more than one, but God is one. 21 Is the law then contrary to the promises of God? Certainly not! For if a law had been given that could give life, then righteousness would indeed be by the law. 22 But the Scripture imprisoned everything under sin, so that the promise by faith in Jesus Christ might be given to those who believe.

Main Idea: God’s covenant promise to Abraham is fulfilled in Christ.

Overview: In this section, Paul explains that the covenant God made with Abraham was not abandoned when God gave the Law through Moses. The law served to highlight further the need for God to fulfill his covenant promise to Abraham, which he did in Jesus Christ. The promised Spirit is given to those who believe in Jesus by faith, making them children united by the Spirit.

Observation and Interpretation

  • For context on promise and law read: Genesis 12:1-9; Genesis 12:15-17; Exodus 20:1-20. Why doesn’t the law invalidate the promise God made to Abraham?

  • In Galatians 3:17-18, what is the good news in this passage? Will God go back on his promise?

  • Explain in your own words we can have confidence in God’s promises to us (Hint: See Hebrews 6:13-18)

  • What purpose does the law serve? How is the promise received? What is the promise? Look back at Galatians 3:14.


  • To be in God’s covenant family, we must believe by faith in Christ. Why is this so hard for us to do? Galatians 3:3 reminds us that we cannot add to faith. What are some ways that you are tempted to add to faith or trust in what you are doing to merit something?

  • Galatians 3:19-22 tells us that Scripture imprisoned everything under sin. Why is this a good thing? When looking to the law reveals our sin more and more, what encouragement do we have?

  • God’s promise to Abraham was fulfilled in Christ and given to us by faith in Jesus. The stars we see are a reminder of the promise (See Genesis 15:5-6). What are things in your life that are reminders of God’s promises to you?

Prayer Point: Spend some time praying and thanking God that he has made his church the children of the promise. Spend some time praying for those who you know that are far from God and that they would place their faith in him.
