Following are a number of back-translations of Romans 4:16:

• Uma: “So, God says we are straight in his sight solely because of our faith, in order that what God promised we receive as a free gift, in order that all the descendants of Abraham receive what God promised. That promise of God is not just for the Jews who know the Lord’s Law. That promise of God is the portion of anyone who believe in God like Abraham. For Abraham is/became the father of us all.” (Source: Uma Back Translation)
• Yakan: “God promised Ibrahim because Ibrahim trusted in him. And the reason why God promised is so that he could-make-certain/prove to all the descendants of Ibrahim that he loved and pitied them/had mercy on them. And that promise of his was not only for the Yahudi, the ones following the law written by Musa, but for everyone who believes God like Ibrahim. Because Ibrahim hep is like the parent of us (incl.) who trust in God.” (Source: Yakan Back Translation)
• Western Bukidnon Manobo: “The reason God has made it so that we can receive what he promised only by faith, is so that this might be possible by means of his kindness, not by means of what we do. And because of this, it is absolutely true that all of us (incl.) who are descendants of Abraham, we will receive what God has promised. And it’s not only the Jews who are under the Law that will receive, but rather anybody who has faith like Abraham had faith, because Abraham has become the ancestor of all who believe, Jew or not Jew.” (Source: Western Bukidnon Manobo Back Translation)
• Kankanaey: “Therefore what God has promised will be fulfilled only to people who believe so that it will be based on his grace/mercy. Because if God’s grace is what it is based on, it will for-sure be fulfilled to all of us who are counted as Abraham’s descendants, not only the Jews who know the law but rather all who believe like the faith of Abraham. Because he is as-if the ancestor of us all.” (Source: Kankanaey Back Translation)
• Tenango Otomi: “This word which God promises is that he will bless those people who believe. It is seen then that it is only by the grace of God that he blesses those who believe. God did not say that only those who do what is said in the law will be blessed by him. Because concerning the person who has faith like the faith that Abraham had, then Abraham becomes like the father of that believer.” (Source: Tenango Otomi Back Translation)
