Romans 3:31 Meaning: Faith Establishes the Law

Two Greek words carry the weight here. First, the verb that is translated "nullify" or "make void", katargeō. It means to render something inoperative, to cancel it, to take away its power. Paul uses the same word in Romans 3:3 for human unbelief that makes God’s faithfulness appear ineffective. He asks: does faith do that to the law? Second, the verb for "establish", histēmi. It means to cause something to stand, to set it upright, to confirm it in a firm position. Paul chooses a word of construction and stability, not demolition. Faith does not knock the law down. It sets it on a solid foundation. The word for "law" (nomos) is debated among commentators, does Paul mean the moral law or the whole Old Testament system? But either way, his point is the same: the law is not discarded. Through faith, its true purpose comes into view.

Christians have understood this verse in slightly different ways. Some, like John Calvin and Matthew Henry, take "law" broadly to include both moral and ceremonial commands; they see Paul defending the whole Old Testament against the charge that faith renders it useless. Others, like Albert Barnes and the Cambridge Bible, argue the context points primarily to the moral law, the commandments that reveal sin. Methodists such as Adam Clarke and John Wesley emphasize that faith establishes the law by fulfilling its demands through Christ and by producing the obedience the law requires. Across these views, all agree on the central point Paul makes: faith and law are allies, not enemies.

Some readers think Paul means that Christians must keep the law to be saved after all, that he is backtracking from "justified by faith apart from works." That misses the force of the verse. Paul is not pulling back. He means that the law is upheld in its proper role: it shows us our sin, and faith in Christ leads us to love what the law commands. As John Wesley put it, faith "establishes the law" by "defending that which the law attests" and "showing how it may be fulfilled in its purity."

This verse meets a real temptation. If you are convinced that you are saved by grace alone, it is easy to treat God’s commands as optional. You may think, "I don't need to worry about obedience; it's all covered." Paul says faith does not work that way. Real faith makes you take the law seriously, not to earn God's favor, but because you now see it as a good gift. This week, when you read a command in Scripture that feels restrictive, ask yourself: How might my trust in Christ actually help me embrace this as good and freeing? Let faith stand the law upright in your heart.
