Romans 4:12-21 Holman Christian Standard Bible (HCSB)
12 And he became the father of the circumcised, who are not only circumcised but who also follow in the footsteps of the faith our father Abraham had while he was still uncircumcised.
The Promise Granted through Faith
13 For the promise to Abraham or to his descendants that he would inherit the world was not through the law, but through the righteousness that comes by faith.[a] 14 If those who are of the law are heirs, faith is made empty and the promise is canceled. 15 For the law produces wrath. And where there is no law, there is no transgression.
16 This is why the promise is by faith, so that it may be according to grace, to guarantee it to all the descendants—not only to those who are of the law[b] but also to those who are of Abraham’s faith. He is the father of us all 17 in God’s sight. As it is written: I have made you the father of many nations.[c] He believed in God, who gives life to the dead and calls things into existence that do not exist. 18 He believed, hoping against hope, so that he became the father of many nations[d] according to what had been spoken: So will your descendants be.[e] 19 He considered[f] his own body to be already dead (since he was about 100 years old) and also considered the deadness of Sarah’s womb, without weakening in the faith. 20 He did not waver in unbelief at God’s promise but was strengthened in his faith and gave glory to God, 21 because he was fully convinced that what He had promised He was also able to perform.
