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

²⁹ And if ye are Christ's, then are ye Abraham's seed, heirs according to promise.

²³ Howbeit the `son' by the handmaid is born after the flesh; but the `son' by the freewoman `is born' through promise.

¹³ For not through the law was the promise to Abraham or to his seed that he should be heir of the world, but through the righteousness of faith.

¹⁴ For if they that are of the law are heirs, faith is made void, and the promise is made of none effect:

¹⁵ for the law worketh wrath; but where there is no law, neither is there transgression.

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, A father of many nations have I made thee) before him whom he believed, `even' God, who giveth life to the dead, and calleth 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 shall thy seed be.

⁸ That is, it is not the children of the flesh that are children of God; but the children of the promise are reckoned for a seed.

⁹ For this is a word of promise, According to this season will I come, and Sarah shall have a son.

²⁵ Ye are the sons of the prophets, and of the covenant which God made with your fathers, saying unto Abraham, And in thy seed shall all the families of the earth be blessed.
