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.
Colossians 2:16-17 Therefore do not let anyone judge you by what you eat or drink, or with regard to a religious festival, a New Moon celebration or a Sabbath day. These are a shadow of the things that were to come; the reality, however, is found in Christ.
