One more thing concerning the Law I didn't mention. I'm afraid you'll think I'm preaching licentiousness here so maybe this will explain it better:
Matthew 5
21 `Ye heard that it was said to the ancients: Thou shalt not kill, and whoever may kill shall be in danger of the judgment;
22 but I -- I say to you, that every one who is angry at his brother without cause, shall be in danger of the judgment, and whoever may say to his brother, Empty fellow! shall be in danger of the sanhedrim, and whoever may say, Rebel! shall be in danger of the gehenna of the fire.

You cannot live a life acceptable to God by following the letter of the Law.
