20 The Law came in so that the transgression would increase … (Romans 5). Also, remember 3:20 — for through the Law comes the knowledge of sin.
I remember a story about a hotel that was built so close to the sea that residents could actually fish from the balcony. The thing is, though, no one ever fished until the hotel manager decided that fishing might cause damage with swinging lures and fish crashing into glass windows below them — so he posted a “No Fishing” sign. That is when the fishing started!
It is the same way with either the Law (the Ten Commandments, etc.) or the Moral Law displayed through human conscience common to all people — that Law betrays our sinful nature by awakening it to do exactly what we are told not to do. God, in His love for us, brought the Law in to show us our sinful nature and thus awaken us to our need for a Savior.
Lord, thank You for awakening us to our need for Jesus. Let us not fall sleep This Day in that understanding. Help us to see our desperate need for You to help us not “go fishing.” Amen.
