Romans 2:18 describes a person who knows what God wants, recognizes what is good, and has been taught by the Jewish law to see the difference. Paul is not praising that knowledge here. He is setting it up, because the verse describes the confidence of someone who thinks knowing the law is the same as living by it. The words are spoken by the apostle Paul, traditionally identified as the author of this letter, and they are addressed to a Jewish reader who relies on the law and feels secure because of it.
And know his will, and approve the things that are excellent, being instructed out of the law…

What Romans 2:18 Means
The verse moves in a sequence. First, the reader “knows his will,” which means understands what God requires. Second, the reader “approves the things that are excellent,” meaning can tell which choices are better and worthy of honor. Third, this knowledge comes from being “instructed out of the law,” so it is not a private feeling but something taught from Scripture. Each step sounds like a good thing, and in a sense it is.
What the verse does not say is that the reader obeys what he knows. Paul leaves that gap open on purpose. Verse 18 describes head knowledge and approval, and the verses that follow press on whether those convictions have reached the way the person lives. The verse therefore does not promise that knowing God’s will makes a person righteous. It only describes what the person has, and leaves the question of practice for the verses around it.
The Context of Romans 2:18
Romans was written by Paul to the believers in Rome, a mixed community of Jewish and Gentile Christians. In chapter 2 he is building a case that everyone, Jew and Gentile alike, stands under God’s judgment, because God judges people by their deeds and not by their heritage. Verses 17 to 20 are a direct address to a person who “bears the name of a Jew” and relies on the law, and Paul uses this figure to show how empty privilege can become when it is not matched by action.
The verses just after this one make the point sharper. Paul asks, “You therefore who teach another, don’t you teach yourself?” and “do you steal?” Read with that in view, verse 18 is the opening of an argument rather than a compliment. The confidence Paul describes is real, but it is being tested against behavior, and that test changes how the verse should be read.
Key Phrases in Romans 2:18
James 1:22
But be doers of the word, and not only hearers, deluding your own selves.
(WEB)
James makes the same point as Romans 2:18 in plainer terms, warning that hearing the word without doing it deceives the hearer. Read together, the two passages show that the New Testament writers consistently treated knowledge of God as something that must become action.
Romans 2:21
You therefore who teach another, don’t you teach yourself? You who preach that a man shouldn’t steal, do you steal?
(WEB)
This is the verse that follows directly after the one under study, where Paul asks whether the teacher who condemns theft is himself a thief. It shows exactly where the argument is heading and why verse 18 cannot be read as a stand-alone compliment.
A Short Prayer From Romans 2:18
Lord, you have given me a clear sense of what is right, and I thank you for teaching me from your word. Please keep that knowledge from becoming a comfortable place where I simply feel secure. Show me the specific choices today where my understanding should change what I do, and give me the courage to act on what I already know. Let my faith be seen in my honesty, my patience, and my kindness toward the people you have placed around me. Amen.
