Session 5 · Romans 3:19-23
We Have Cause to Be Uneasy
The Law we long to keep and cannot, and why that is where the good news begins
Book reading: Mere Christianity, Book One, Chapter 5 (We Have Cause to Be Uneasy)
Book One closes with a chapter that does not let you get comfortable. Lewis counters three common objections to Christianity, and then he makes a harder point. The God behind the Moral Law is both attractive and frightening. We desire the goodness we cannot live up to, and that leaves us unsettled. Lewis argues that Christianity only really makes sense to someone who feels the Law and also feels their own failure to keep it.
Paul says something close in Romans 3. "Whatever the law says it speaks to those who are under the law, so that every mouth may be stopped, and the whole world may be held accountable to God." Think about "every mouth may be stopped." It is the moment the excuses run out. Remember the inner voice from Romans 2 that "excuses"? Paul says there comes a point when that voice has nothing left to say.
He also explains what the law is for: "by works of the law no human being will be justified in his sight, since through the law comes knowledge of sin." The law works like a mirror. A mirror can show you that your face is dirty, but it cannot wash it. That is exactly the unsettled place Lewis describes. The standard is real, we want to meet it, and we can't.
If Paul stopped there, it would be a very bleak passage. But look at what happens in verse 21: "But now the righteousness of God has been manifested apart from the law." That little phrase "But now" turns the page. God's own righteousness is shown, "through faith in Jesus Christ for all who believe." And then comes the great leveler: "For there is no distinction: for all have sinned and fall short of the glory of God." The bad news is shared by everyone. So is the offer.
This is how to receive the unease Lewis describes. It is not meant to push you into despair or into frantic self-improvement. It is meant to make you ready for good news that comes from outside yourself. If you never felt the gap, a rescue would seem pointless. Feeling it is, strangely, the beginning of being able to receive help. Book Two will turn to what Christians actually believe, and the unease you have been tracing is the reason that question matters.
One caution. There is a difference between honest unease and a crushing, constant sense of condemnation that never lets up. If guilt feels like it is swallowing you, or if you can't stop replaying failures, please talk to a pastor, counselor or trusted friend. The goal of this chapter is a clear look at your need, not a heavier load.
Key idea
Lewis argues the God behind the Moral Law both draws and frightens us, because we long for goodness we cannot keep, and that unease is what makes Christianity make sense; Paul's "But now" shows it as the doorway to the gospel, not a reason for despair.
Questions to consider
- Where do you feel the gap most sharply between the person you want to be and the person you actually are? How do you usually respond to that gap?
- Paul says the law shows us our sin but cannot fix it. How does it change things to see the unease as a doorway to good news, not just a verdict?
Journal prompt
Write honestly about one place where you long for goodness you can't seem to live out. Then write a short prayer, in your own words, asking God for the help that Romans 3:21-22 says comes from outside yourself.
Practice
Dose: 10 minutes, once. 1) Read Romans 3:19-23 slowly twice. 2) Mark the "But now" in verse 21. 3) Write one sentence naming a gap you feel between the standard and your life. 4) Write one sentence beginning with "But now," naming a way God's help could reach into that gap. 5) If guilt feels heavy or unrelenting, share this with a pastor, counselor or trusted friend.
