Week 3: A Covenant You Carry in Your Body (Genesis 17:1–14)

The Big Idea

God restates his covenant with Abram, gives him a new name, and calls the covenant everlasting. Then he gives a sign that Abraham's household will carry in their own bodies. God's covenant is not only a promise in the sky or a ceremony in the past. It reaches into ordinary life and marks a people as belonging to him.

Before You Read

Years have passed since Genesis 15. In chapter 16, Abram and Sarai tried to secure the promise their own way, and Hagar bore Abram a son, Ishmael, when Abram was eighty-six. Now Abram is ninety-nine, and thirteen more years have gone by. Circumcision was practiced by some other peoples in the ancient world, but God gives it a new meaning here: it becomes the sign of his covenant with Abraham and his offspring. Notice that it is given to a man who already believed God (15:6). The sign follows the promise; it does not purchase it.

Read

Read Genesis 17:1–14 slowly, twice, once aloud. Listen for how often God says "my." It may help to read verses 1–8 and then pause before reading 9–14.

Observe

1. How old is Abram, and how does God introduce himself in verse 1? What two things does God call Abram to do?
2. How does Abram respond physically in verse 3?
3. Mark every "I will" God says in verses 2–8. What does God promise?
4. What new name does Abram receive, and what does verse 5 say it means?
5. Verse 4 begins with God's side of the covenant, and verse 9 turns to Abraham's side. What is each side?
6. Who must receive the sign of circumcision (vv. 10–13)? Note who is included beyond Abraham's own sons.
7. How many times does the word everlasting appear? What is called everlasting?
8. What happens, according to verse 14, to the one who refuses the sign? How is that person described?

A Word to Notice

Berit (beh-REET), covenant, appears again and again in these fourteen verses, far more often than any other key word. And over and over, God calls it my covenant. That small word matters. This is not a shared project that God and Abraham design together. God owns it, defines it, and guarantees it. Even the sign belongs to him. Verse 13 says his covenant will be in their flesh. Abraham's family would carry God's covenant in their bodies, not as a decoration but as a mark of ownership: you are mine. The obligations given to Abraham are real, but they are a response to a covenant God has already made and called everlasting.

Interpret

1. God calls Abram to "walk before me, and be blameless." How does this fit with what God already promised in Genesis 15, which depended on God alone?Consider: God's promise does not make obedience pointless; it makes obedience possible and meaningful. Abraham is called to live as someone who belongs to God, in response to grace, not to earn it.

2. Why do you think God changes Abram's name at this point? What would it have been like for a childless ninety-nine-year-old to introduce himself by a name that announced he was the father of many nations?Consider: Every time someone said his name, Abraham would hear God's promise. It was faith spoken out loud before there was any visible proof.

3. Why would God put the sign of his covenant on the body, in a place no one else sees, rather than on a doorpost or a monument?Consider: In a chapter full of promises about offspring (vv. 2, 6–7), the sign is placed where it touches the next generation. It was personal and permanent: the family line itself belonged to God.

4. Verse 14 says the one who refuses the sign will be cut off from his people. How does that phrase connect with last week's word, karat, to cut?Consider: It is the same verb. The covenant was cut in blood; refusing its sign means being cut off from the people. Covenant is gracious, but it is never casual.

5. Cross-reference: Read Deuteronomy 10:16, Deuteronomy 30:6, and Romans 2:28–29. What does the Bible eventually say the outward sign was always pointing toward?Consider: Even in Moses' day, God called for a circumcised heart, and promised that he himself would do it. The outward mark pointed to an inward change only God can work. We will return to this in Week 11.

Apply: Let the Text Read You

• Abraham fell on his face before God said another word. When you come to God, what is your posture: hurried, guarded, bargaining, worshipful? What does your posture tell you?
• God gave Abraham a new name while the promise was still unfulfilled. Is there a name you carry ("failure," "too late," "not enough") that God has not given you? What does he call you instead?
• Belonging to God reaches into the body and into ordinary life. Where in your daily routine, work, or home do you live as though God's claim on you stops?
• How does it feel to hear God say my covenant, not our arrangement? Does that sound like pressure, or like security?

Pray

God Almighty, you call me to walk before you, and you have already promised to be my God. Thank you that I belong to you, not by my strength, but by your covenant. Mark my whole life as yours, inside and out. Amen.

For Groups (optional)

• Be sensitive: this passage involves a physical, private sign. Keep the focus on what the sign meant, and let the text's seriousness come through without awkwardness.
• Discussion starter: What are some ways people mark that they belong (a uniform, a brand, a wedding ring, a family name)? What does each say about the person who wears it?
• Compare Genesis 15 and 17 side by side. What stays the same? What is new?
