The Law of God is radically important for you as a Christian - There are 220 references to the Law of Moses in the New Testament that’s almost as many as there are in the OT. It’s practically impossible to understand the NT unless you have some grasp of the Law.
Missionally - the Law is said to be written on heart of every person you come in contact with. The law is the Evangelist’s best friend. Last week when Mark Witt preached - I hope you recognized how frequently be mentioned the 10 commandments. Why? That is the birthplace of conviction.
