James 2:8-11

If you really obey the Royal Law found in Scripture that says, "Love your neighbor as yourself," you are doing the right thing. But if you show favoritism, you are committing a sin and are convicted by the Law as a lawbreaker. For whoever keeps the whole Law, except for one point, is still guilty and a lawbreaker. For the same GOD who said, "Do not commit adultery," also said, "Do not murder." So if you murder someone, you are a lawbreaker, even if you never break any other Law.
