Romans 4:16 teaches that God’s promise is received by faith and is given as a gift of grace, so that it stands firm for everyone who trusts God, not only for those who keep the law. Paul wrote this letter to the churches in Rome, and he is making a point about how a person comes into relationship with God and inherits what God has promised.
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 what Paul has just said about Abraham. Because the promise was never earned by good works or by keeping a code of rules, it comes to people through trust. Faith is the means by which the promise is taken hold of, and it is the reason the promise can be received at all.
The next phrase, “that it may be according to grace,” explains why faith is the path. Grace is God’s free kindness, given without being owed. If the promise depended on performance, it would be a wage. Because it depends on grace and is received by faith, no one can boast about earning it, and everyone who believes has the same footing before God.
Paul then says the promise “may be sure to all the offspring.” The word “sure” means firm and secure. The verse does not promise that every person automatically gets everything they want. It promises that God’s word to Abraham will not fail, and that those who share Abraham’s kind of trust are included in what God has pledged to him.
The Context of Romans 4:16
Paul wrote Romans to a mixed group of believers in Rome, some of whom came from a Jewish background and some from a Gentile one. Many of the Jewish believers took pride in the law and in their descent from Abraham, and the question of who truly belongs to God’s family was a live issue. In this passage Paul uses Abraham as his main example, showing that Abraham was counted righteous before the law was given, through believing God.
The verses just before and after make the argument clear. In verse 15 Paul notes that the law brings wrath because it exposes sin, so relying on the law alone cannot secure the promise. Verse 17 then quotes God’s word that Abraham would become a father of many nations, and Paul moves straight into Abraham’s trust in the God who gives life to the dead. Read in that setting, verse 16 is the conclusion of an argument: the promise comes through faith so that it can rest on grace and reach all of Abraham’s true children, Jew and Gentile alike.

These verses say plainly that salvation is a gift of grace received through faith, not something earned by works. They express the same pattern Paul develops in Romans 4, showing that God’s kindness and our trust are the foundation of our standing before him.
Genesis 15:6
He believed in the LORD, who credited it to him for righteousness.

This is the verse Paul relies on in Romans 4 to show that Abraham was counted righteous through believing God. Reading it alongside Romans 4:16 helps you see the original story behind Paul’s argument about faith and promise.
A Short Prayer From Romans 4:16
Father, thank you that your promises do not depend on my ability to earn them. I confess how often I try to secure your favor through my own effort and how quickly I forget that you give freely. Help me to receive your grace with simple trust, the way Abraham believed you when the way forward was unclear. Strengthen my faith today so that I rest in what you have promised, and let your steady kindness shape how I live and how I treat others. Amen.
