Romans 4:13-17 New American Standard Bible (NASB)
13 For the promise to Abraham or to his [a]descendants that he would be heir of the world was not [b]through the Law, but through the righteousness of faith. 14 For if those who are [c]of the Law are heirs, faith is made void and the promise is nullified; 15 for the Law brings about wrath, but where there is no law, there also is no violation.
16 For this reason it is [d]by faith, in order that it may be in accordance with grace, so that the promise will be guaranteed to all the [e]descendants, not only to [f]those who are of the Law, but also to [g]those who are 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 you”) in the presence of Him whom he believed, even God, who gives life to the dead and [h]calls into being that which does not exist.
Romans 4:13-17 Amplified Bible (AMP)
13 For the promise to Abraham or to his descendants that he would be heir of the world was not through [observing the requirements of] the Law, but through the righteousness of faith. 14 If those who are [followers] of the Law are [the true] heirs [of Abraham], then faith [leading to salvation] is of no effect and void, and the promise [of God] is nullified. 15 For the Law results in [God’s] wrath [against sin], but where there is no law, there is no violation [of it either].
16 Therefore, [inheriting] the promise depends entirely on faith [that is, confident trust in the unseen God], in order that it may be given as an act of grace [His unmerited favor and mercy], so that the promise will be [legally] guaranteed to all the descendants [of Abraham]—not only for those [Jewish believers] who keep the Law, but also for those [Gentile believers] who share the faith of Abraham, who is the [spiritual] father of us all— 17 (as it is written [in Scripture], “I have made you a father of many nations”) in the sight of Him in whom he believed, that is, God [a]who gives life to the dead and calls into being that which does not exist.
