²⁸ Now we, brothers, as Isaac was, are children of promise.

²⁹ If you are Christ's, then you are Abraham's seed and heirs according to promise.

²³ However, the son by the handmaid was born according to the flesh, but the son by the free woman was born through promise.

¹³ For the promise to Abraham and to his seed that he should be heir of the world wasn't through the law, but through the righteousness of faith.

¹⁴ For if those who are of the law are heirs, faith is made void, and the promise is made of no effect.

¹⁵ For the law works wrath, for where there is no law, neither is there disobedience.

¹⁶ For this cause it is of faith, that it may be according to grace, to the end that the promise may be sure to all the seed, not to that only which is of the law, but to that also which is of the faith of Abraham, who is the father of us all.

¹⁷ As it is written, "I have made you a father of many nations." This is in the presence of him whom he believed: God, who gives life to the dead, and calls the things that are not, as though they were.

¹⁸ Who in hope believed against hope, to the end that he might become a father of many nations, according to that which had been spoken, "So will your seed be."

⁸ That is, it is not the children of the flesh who are children of God, but the children of the promise are counted as a seed.

⁹ For this is a word of promise, "At the appointed time I will come, and Sarah will have a son."

²⁵ You are the children of the prophets, and of the covenant which God made with our fathers, saying to Abraham, 'In your seed will all the families of the earth be blessed.'
