Joe Thorn, author of the excellent little book Note to Self, talks about the law and the gospel.
What is the purpose of the law? The law shows us three things:
- The law shows us what is right (God’s will/way): Ps. 119:1, 23, 44, 47; Rom. 7:12
- The law shows us what is wrong (our sin and corruption): Rom. 3:20; 7:7-12; James. 2:10
- The law shows us what is needed (redemption): Rom. 7:13-18; Gal. 3:19
