James 2:8-13

So if you perfect the regal law, according to the Scriptures, "You shall love your neighbor as yourself," then you do well. But if you show favoritism to persons, then you commit a sin, having been convicted again by the law as transgressors. Now whoever has observed the whole law, yet who offends in one matter, has become guilty of all. For he who said, "You shall not commit adultery," also said, "You shall not kill." So if you do not commit adultery, but you kill, you have become a transgressor of the law. So speak and act just as you are beginning to be judged, by the law of liberty. For judgment is without mercy toward him who has not shown mercy. But mercy exalts itself above judgment.
