Romans 4:16-21 This is why righteousness is of faith, that it may be a free gift; so that the promise stands firm to all Abraham's posterity; not to his children of his faith. For in the sight of the God in whom he believed, who gives life to the dead, and calls into being that which is not, Abraham is the father of us all both Jews and Gentiles,

MNT⁽ⁱ⁾ ¹⁶ This is why righteousness is of faith, that it may be a free gift; so that the promise stands firm to all Abraham's posterity; not to his children of his faith. For in the sight of the God in whom he believed, who gives life to the dead, and calls into being that which is not, Abraham is the father of us all both Jews and Gentiles, ¹⁷ as it is written, I have made you a father of many nations. ¹⁸ For Abraham, hoping against hope, had faith to the end that he might become a father of many nations, according to that which had been spoken, So numberless shall your descendants be. ¹⁹ Though he was about a hundred years old, his faith did not fail him when he regarded his own body, now as good as dead. and remembered Sarah's barrenness. ²⁰ Nor did he with regard to the promise of God waver in unbelief, but he waxed strong in faith, while he gave God glory, ²¹ and was fully persuaded that what God had promised, he was able also to perform.
