¹ Now the Lord was gracious to Sarah as he had said, and the Lord did for Sarah what he had promised. ² Sarah became pregnant and bore a son to Abraham in his old age, at the very time God had promised him. ³ Abraham gave the name Isaac to the son Sarah bore him. ⁴ When his son Isaac was eight days old, Abraham circumcised him, as God commanded him. ⁵ Abraham was a hundred years old when his son Isaac was born to him.

⁶ Sarah said, “God has brought me laughter, and everyone who hears about this will laugh with me.” ⁷ And she added, “Who would have said to Abraham that Sarah would nurse children? Yet I have borne him a son in his old age.”

⁸ The child grew and was weaned, and on the day Isaac was weaned Abraham held a great feast. ⁹ But Sarah saw that the son whom Hagar the Egyptian had borne to Abraham was mocking, ¹⁰ and she said to Abraham, “Get rid of that slave woman and her son, for that woman’s son will never share in the inheritance with my son Isaac.”

¹¹ The matter distressed Abraham greatly because it concerned his son. ¹² But God said to him, “Do not be so distressed about the boy and your slave woman. Listen to whatever Sarah tells you, because it is through Isaac that your offspring will be reckoned. ¹³ I will make the son of the slave into a nation also, because he is your offspring.”

¹⁴ Early the next morning Abraham took some food and a skin of water and gave them to Hagar. He set them on her shoulders and then sent her off with the boy. She went on her way and wandered in the Desert of Beersheba.

¹⁵ When the water in the skin was gone, she put the boy under one of the bushes. ¹⁶ Then she went off and sat down about a bowshot away, for she thought, “I cannot watch the boy die.” And as she sat there, she began to sob.

¹⁷ God heard the boy crying, and the angel of God called to Hagar from heaven and said to her, “What is the matter, Hagar? Do not be afraid; God has heard the boy crying as he lies there. ¹⁸ Lift the boy up and take him by the hand, for I will make him into a great nation.”

¹⁹ Then God opened her eyes and she saw a well of water. So she went and filled the skin with water and gave the boy a drink.

²⁰ God was with the boy as he grew up. He lived in the desert and became an archer. ²¹ While he was living in the Desert of Paran, his mother got a wife for him from Egypt.

¹ I speak the truth in Christ—I am not lying, my conscience confirms it through the Holy Spirit— ² I have great sorrow and unceasing anguish in my heart. ³ For I could wish that I myself were cursed and cut off from Christ for the sake of my people, those of my own race, ⁴ the people of Israel. Theirs is the adoption to sonship; theirs the divine glory, the covenants, the receiving of the law, the temple worship and the promises. ⁵ Theirs are the patriarchs, and from them is traced the human ancestry of the Messiah, who is God over all, forever praised! Amen.

⁶ It is not as though God’s word had failed. For not all who are descended from Israel are Israel. ⁷ Nor because they are his descendants are they all Abraham’s children. On the contrary, “It is through Isaac that your offspring will be reckoned.” ⁸ In other words, it is not the children by physical descent who are God’s children, but it is the children of the promise who are regarded as Abraham’s offspring. ⁹ For this was how the promise was stated: “At the appointed time I will return, and Sarah will have a son.”

¹⁰ Not only that, but Rebekah’s children were conceived at the same time by our father Isaac. ¹¹ Yet, before the twins were born or had done anything good or bad—in order that God’s purpose in election might stand: ¹² not by works but by him who calls—she was told, “The older will serve the younger.” ¹³ Just as it is written: “Jacob I loved, but Esau I hated.”

¹⁴ What then shall we say? Is God unjust? Not at all! ¹⁵ For he says to Moses,

“I will have mercy on whom I have mercy,
     and I will have compassion on whom I have compassion.”

¹⁶ It does not, therefore, depend on human desire or effort, but on God’s mercy. ¹⁷ For Scripture says to Pharaoh: “I raised you up for this very purpose, that I might display my power in you and that my name might be proclaimed in all the earth.” ¹⁸ Therefore God has mercy on whom he wants to have mercy, and he hardens whom he wants to harden.

¹⁹ One of you will say to me: “Then why does God still blame us? For who is able to resist his will?” ²⁰ But who are you, a human being, to talk back to God? “Shall what is formed say to the one who formed it, ‘Why did you make me like this?’” ²¹ Does not the potter have the right to make out of the same lump of clay some pottery for special purposes and some for common use?

²² What if God, although choosing to show his wrath and make his power known, bore with great patience the objects of his wrath—prepared for destruction? ²³ What if he did this to make the riches of his glory known to the objects of his mercy, whom he prepared in advance for glory— ²⁴ even us, whom he also called, not only from the Jews but also from the Gentiles? ²⁵ As he says in Hosea:

“I will call them ‘my people’ who are not my people;
    and I will call her ‘my loved one’ who is not my loved one,”

²⁶ and,

“In the very place where it was said to them,
    ‘You are not my people,’
    there they will be called ‘children of the living God.’”

²⁷ Isaiah cries out concerning Israel:

“Though the number of the Israelites be like the sand by the sea,
    only the remnant will be saved.
²⁸  For the Lord will carry out
    his sentence on earth with speed and finality.”

²⁹ It is just as Isaiah said previously:

“Unless the Lord Almighty
    had left us descendants,
we would have become like Sodom,
    we would have been like Gomorrah.”
