“Desiring to justify himself…” We all want our own way to justification, but there’s only one way.
This is Romans in 5. You’re going to sin. But God’s got some Good News. You’re going to be saved, and you’re going to learn to fight sin. But you’ll still sin and when you do, what’s going to happen? God’s got more good news for you to keep on saving you! That’s the book of Romans!
