Before Jesus Christ came, the law was a necessity and a way of judgement. But now, faith in Jesus Christ is what you require. Galatians 3:19 What purpose then does the law serve? It was added because of transgressions, till the Seed should come to whom the promise was made; and it was appointed through angels by the hand of a mediator.
The law only applies when you are alive but since you died with Christ, the law no longer have a hold on you. Romans 10:4 For Christ is the end of the law for righteousness to everyone who believes.
