God’s covenant with Abraham

17 When Abram was 99 years old, the Lord appeared to Abram and said to him, “I am El Shaddai.^[a] Walk with me and be trustworthy. ² I will make a covenant between us and I will give you many, many descendants.” ³ Abram fell on his face, and God said to him, ⁴ “But me, my covenant is with you; you will be the ancestor of many nations. ⁵ And because I have made you the ancestor of many nations, your name will no longer be Abram^[b] but Abraham.^{[c] 6} I will make you very fertile. I will produce nations from you, and kings will come from you. ⁷ I will set up my covenant with you and your descendants after you in every generation as an enduring covenant. I will be your God and your descendants’ God after you.

¹⁵ God said to Abraham, “As for your wife Sarai, you will no longer call her Sarai. Her name will now be Sarah. ¹⁶ I will bless her and even give you a son from her. I will bless her so that she will become nations, and kings of peoples will come from her.”

Abraham’s promise is received through faith

¹³ The promise to Abraham and to his descendants, that he would inherit the world, didn’t come through the Law but through the righteousness that comes from faith. ¹⁴ If they inherit because of the Law, then faith has no effect and the promise has been canceled. ¹⁵ The Law brings about wrath. But when there isn’t any law, there isn’t any violation of the law. ¹⁶ That’s why the inheritance comes through faith, so that it will be on the basis of God’s grace. In that way, the promise is secure for all of Abraham’s descendants, not just for those who are related by Law but also for those who are related by the faith of Abraham, who is the father of all of us. ¹⁷ As it is written: I have appointed you to be the father of many nations.^[a] So Abraham is our father in the eyes of God in whom he had faith, the God who gives life to the dead and calls things that don’t exist into existence. ¹⁸ When it was beyond hope, he had faith in the hope that he would become the father of many nations, in keeping with the promise God spoke to him: That’s how many descendants you will have.^{[b] 19} Without losing faith, Abraham, who was nearly 100 years old, took into account his own body, which was as good as dead, and Sarah’s womb, which was dead. ²⁰ He didn’t hesitate with a lack of faith in God’s promise, but he grew strong in faith and gave glory to God. ²¹ He was fully convinced that God was able to do what he promised. ²² Therefore, it was credited to him as righteousness.

²³ But the scripture that says it was credited to him^[c] wasn’t written only for Abraham’s sake. ²⁴ It was written also for our sake, because it is going to be credited to us too. It will be credited to those of us who have faith in the one who raised Jesus our Lord from the dead. ²⁵ He was handed over because of our mistakes, and he was raised to meet the requirements of righteousness for us.

³¹ Then Jesus began to teach his disciples: “The Human One^[a] must suffer many things and be rejected by the elders, chief priests, and the legal experts, and be killed, and then, after three days, rise from the dead.” ³² He said this plainly. But Peter took hold of Jesus and, scolding him, began to correct him. ³³ Jesus turned and looked at his disciples, then sternly corrected Peter: “Get behind me, Satan. You are not thinking God’s thoughts but human thoughts.”

³⁴ After calling the crowd together with his disciples, Jesus said to them, “All who want to come after me must say no to themselves, take up their cross, and follow me. ³⁵ All who want to save their lives will lose them. But all who lose their lives because of me and because of the good news will save them. ³⁶ Why would people gain the whole world but lose their lives? ³⁷ What will people give in exchange for their lives? ³⁸ Whoever is ashamed of me and my words in this unfaithful and sinful generation, the Human One^[b] will be ashamed of that person when he comes in the Father’s glory with the holy angels.”
