Romans 4:16 teaches that God’s promise comes to us by faith, not by our ability to keep the law, so that it rests on God’s grace and cannot fail. Paul wrote this letter to the believers in Rome, a mixed congregation of Jewish and Gentile Christians, and in this verse he explains why the promise made to Abraham belongs to everyone who trusts God the way Abraham did.
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 offspring, 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.

What Romans 4:16 Means
The opening phrase, “For this cause it is of faith,” points back to the argument Paul has just made. If the promise depended on earning God’s approval by obeying the law, then it would depend on us, and we would never be fully certain of receiving it. Faith is the open hand that receives what God gives, so the promise is tied to trust rather than performance.
The phrase “that it may be according to grace” explains the purpose. Grace is God giving what we could never deserve or achieve. When the promise flows from grace, its size is set by God’s generosity, not by the quality of our record. The verse does not say that obedience is unimportant. It says that obedience cannot be the foundation of the promise.
The final part, “to the end that the promise may be sure to all the offspring,” describes the result. Because the promise rests on grace received through faith, it is secure for everyone who shares Abraham’s trust, whether they come from the Jewish law tradition or not. The verse does not promise that every believer will feel confident or never struggle, but it does say the promise itself is anchored in something stronger than human effort.
The Context of Romans 4:16
The letter to the Romans was written by the apostle Paul, most likely from Corinth around the middle of the first century. Paul’s main concern in chapters 1 through 8 is how a person is made right with God, and he keeps returning to the example of Abraham, the ancestor both Jews and Christians honored. In the verses just before this one, Paul argues that the promise God made to Abraham came before the law was given, so the law could not be the basis for it.
Verses 13 through 15 set up the logic. Paul says that if inheritance came through the law, faith would be empty and the promise would be void, because the law tends to bring wrath when it is broken. Verse 16 is the conclusion of that argument. Read in this setting, the verse is not a general statement about faith in the abstract. It is a specific answer to the question of how the promise to Abraham can be guaranteed to people who were never under the law at all.
Key Phrases in Romans 4:16
Ephesians 2:8-9
8 For by grace you have been saved through faith, and that not of yourselves; it is the gift of God, 9 not of works, that no one would boast.
(WEB)
These verses state plainly that salvation comes by grace through faith and not by works. They echo the same logic Paul builds in Romans 4, showing that the gift is not something people can claim as their own achievement.
Galatians 3:7
Know therefore that those who are of faith, the same are children of Abraham.
(WEB)
Paul makes the same connection in Galatians, teaching that those who have faith are the true children of Abraham. This verse helps explain why the promise reaches beyond Abraham’s physical descendants to all who share his trust.
A Short Prayer From Romans 4:16
Lord, thank you that your promises do not depend on my ability to keep every rule perfectly. Help me to receive your grace the way Abraham received your word, with a trust that does not waver when I cannot see the outcome. When I feel that I must earn your favor, remind me that you have already given me a place in your family through faith. Strengthen my faith today, and let it rest on your faithfulness rather than on my own performance. Amen.
