A Catalogue of Sins—Not that Important?

Have you created a catalog of sins that distinguishes between important and not so important actions? Does the Bible teach the concept of the seven deadly sins? Or is every sin wrong and an abomination in God's eyes? What does God call sin and an abomination anyway? And what does God say who will not inherit the Kingdom of God? Why does God designate certain character traits as “most important” in the law? And do you love God and neighbor when you break the spiritual law of the Ten Commandments?
