Week 10 Discussion Guide: Covenant of Promise

Opening

Begin by reciting this week’s memory verse together:

“And he believed the LORD, and he counted it to him as righteousness.” – Genesis 15:6 (ESV)

Have you ever trusted someone’s promise when every visible circumstance said it could not be kept? What did that trust cost you – and what did it reveal about the one who made the promise?

Review: The Big Picture

This week we followed the Abrahamic covenant from spoken promise to sworn oath, from starlit faith to blood-sealed ceremony, from human scheming to divine renaming. In Genesis 15, Abram voices his doubt aloud – he is childless, aging, and the promise feels hollow – and God responds not with rebuke but with stars: “So shall your offspring be.” Abram believes, and God credits that belief as righteousness, establishing the principle that will undergird the entire gospel. Then God formalizes the covenant in a ceremony of halved animals and self-maledictory oath, walking the path alone while Abram sleeps – a unilateral commitment guaranteed by God’s own life. Genesis 16 shows the wreckage of impatience: Sarai’s scheme, Hagar’s suffering, Ishmael’s birth outside the line of promise. And Genesis 17 brings the full revelation – El Shaddai appears, Abram becomes Abraham, circumcision is instituted as the covenant sign, and the impossible is announced: ninety-year-old Sarah will bear a son named “Laughter.”

Discussion Questions

Day 1: “Look toward heaven” (Genesis 15:1-6)

1. The Honesty of Doubt. Abram does not doubt quietly. He confronts God: “O Lord GOD, what will you give me, for I continue childless?” (15:2). What does it reveal about the nature of covenant relationship that God invites – even receives – this kind of raw honesty? How does this compare with the sanitized prayers we often offer?

2. Faith Counted as Righteousness. Genesis 15:6 is the first time Scripture explicitly connects belief with righteous standing before God. The Hebrew he’emin means to lean one’s full weight on something. Paul will later build the entire doctrine of justification on this verse (Romans 4:3; Galatians 3:6). Why does the timing matter – that this declaration comes before circumcision, before Sinai, before any system of merit?

3. Stars and Offspring. God takes Abram outside and points to the night sky. The promise is not abstract theology but a physical act – looking up, counting, failing to count. Why do you think God chose something visible and overwhelming rather than simply speaking the promise again?

Day 2: The Covenant Ceremony (Genesis 15:7-21)

1. God Alone Passes. In the ancient Near Eastern covenant ritual, both parties walked between the divided animals, invoking the curse upon themselves: “May I be torn apart if I break this oath.” But Abram sleeps, and God alone passes through as a smoking fire pot and flaming torch. What are the implications of a covenant in which only one party takes the oath? What does this tell us about who bears the cost if the covenant is broken?

2. Dreadful Darkness. Before the fire appears, “a dreadful and great darkness fell upon him” (15:12), and God speaks of four hundred years of slavery. Why does the covenant ceremony include a preview of suffering? What does it mean that promise and pain coexist in the same scene?

Day 3: Hagar and Ishmael (Genesis 16:1-16)

1. Helping God Out. Sarai’s plan to give Hagar to Abram is culturally reasonable – ancient custom endorsed it. Yet the consequences are devastating: rivalry, cruelty, exile. Where in your own life have you been tempted to engineer the fulfillment of God’s promises rather than wait for his timing? What were the results?

2. The God Who Sees. Hagar names God El Roi – “a God of seeing” (16:13). She is a foreign slave woman, cast out and pregnant, and yet God finds her, speaks to her, and makes promises about her son. What does God’s pursuit of Hagar reveal about the reach of his grace – even outside the chosen line of promise?

Day 4: Abram Becomes Abraham (Genesis 17:1-14)

1. El Shaddai and the Walk. God reveals himself as El Shaddai – God Almighty – and commands, “Walk before me, and be blameless” (17:1). The demand for blamelessness comes twenty-four years after the original call. Why does God wait so long to issue this charge? And what kind of “blamelessness” is possible for a man who has already schemed and failed?

2. The Sign in the Flesh. Circumcision is given as a sign of the covenant – physical, permanent, intimate, and painful. It comes after the covenant is sworn, not as a condition for entering it. What is the significance of a covenant sign that marks the body? How does Paul’s argument in Romans 4:10-11 – that Abraham was declared righteous before circumcision – reshape our understanding of signs and sacraments?

Day 5: Sarah Will Bear a Son (Genesis 17:15-27)

1. Abraham’s Laughter. Abraham falls on his face and laughs: “Shall a child be born to a man who is a hundred years old?” (17:17). God does not rebuke the laughter. Instead, he names the child Yitschaq – “he laughs.” What does it tell us about God’s character that he writes human incredulity into the story rather than erasing it?

2. Ishmael’s Blessing. Abraham pleads, “Oh that Ishmael might live before you!” (17:18). God blesses Ishmael generously – twelve princes, a great nation – but the covenant runs through Isaac alone. How do you understand the tension between God’s generous provision for Ishmael and the exclusive election of Isaac? What does this narrowing of the promise line accomplish?

Synthesis

1. From Stars to Cross. The fire that passed between the pieces in Genesis 15 is the same divine presence that will bear the penalty for covenant-breaking at Calvary. How does the unilateral covenant ceremony of Genesis 15 help you understand why the cross was necessary – not as an afterthought but as the fulfillment of an oath God swore in the darkness of an ancient night?

Going Deeper: Connections Across the Week

• The Sequence of Faith, Covenant, and Sign. Genesis 15-17 presents a deliberate order: first belief is credited as righteousness (15:6), then the covenant is sworn in blood (15:7-21), and finally the sign of circumcision is given (17:9-14). Paul identifies this sequence as theologically decisive – Abraham was justified by faith before he was circumcised, proving that right standing with God has always rested on trust, not ritual (Romans 4:9-12). The sign confirms what faith has already received. It does not create it. This sequence anticipates the New Testament relationship between faith and baptism, and it dismantles every system that places human action before divine grace.

• The Cost of Impatience. Hagar and Ishmael stand as a permanent testimony to what happens when human engineering replaces divine timing. The plan was culturally acceptable. The logic was sound. And the consequences – rivalry between Sarah and Hagar, conflict between Isaac and Ishmael, and a geopolitical tension that persists to this day – are centuries long. Yet God does not abandon the wreckage. He sees Hagar. He blesses Ishmael. He holds the promise steady while the humans stumble around it. The grace that covers impatience is as real as the grace that credits faith, and both flow from the same unilateral oath.

• Impossible Births and the Pattern of Promise. Isaac is the first child in Scripture whose birth is declared biologically impossible and then delivered by divine command. The pattern will repeat – with Jacob’s wife Rachel, with Hannah, with the Shunammite woman, with Elizabeth – each barren womb a smaller rehearsal for the one birth that will shatter every category: a virgin conceives, and the son she bears is the Promise itself (Matthew 1:23). God’s habit of working through impossibility is not dramatic flair. It is theological method. Children who cannot be explained by natural means are children whose existence testifies that God does what God says.

Application

• Personal: Identify one promise of God – from Scripture, not your own wishes – that you are struggling to believe because the visible evidence contradicts it. Write it down. Place it where you will see it daily. Let Abram under the stars be your model: belief does not require understanding. It requires looking where God points.

• Relational: The story of Hagar reminds us that God sees the overlooked, the displaced, the used. Is there someone in your life who has been marginalized or forgotten? This week, be the one who sees them – not as a project but as a person God has pursued.

• Formational: Circumcision was a daily, bodily reminder of covenant belonging. What practice in your own life serves as a tangible reminder that you belong to God? If no such practice exists, consider adopting one – a morning prayer, a weekly fast, a memorized verse spoken aloud – that writes covenant identity into the rhythm of your days.

Closing Prayer

Father, you are the God who takes the oath and bears the cost. You walked between the pieces while Abraham slept. You swore on your own life that the covenant would stand, knowing that the penalty for its breaking would fall on you. We confess that we are more like Abram in Genesis 16 than in Genesis 15 – quick to scheme, slow to wait, prone to engineer what you have promised to provide. Teach us the faith that looks at the stars and believes. Remind us that our righteousness rests not on our consistency but on your verdict – the same verdict spoken over a childless man under a Mesopotamian sky and sealed in the blood of your Son. In the name of Jesus, who is the fire and the lamb and the promise kept, amen.

Looking Ahead

Next week we turn to Genesis 18-20, where three visitors arrive at Abraham’s tent, Sarah laughs at the promise of a son, and Abraham intercedes boldly for the doomed cities of the plain. We will witness the destruction of Sodom and Gomorrah, the rescue of Lot, and – astonishingly – Abraham repeating the same failure he committed in Egypt. The question that will frame the week is one Abraham himself asks: “Shall not the Judge of all the earth do what is just?”
