James 2:8–13 (ESV)
 If you really fulfill the royal law according to the Scripture, “You shall love your neighbor as yourself,” you are doing well.  But if you show partiality, you are committing sin and are convicted by the law as transgressors.  For whoever keeps the whole law but fails in one point has become guilty of all of it.  For he who said, “Do not commit adultery,” also said, “Do not murder.” If you do not commit adultery but do murder, you have become a transgressor of the law.  So speak and so act as those who are to be judged under the law of liberty.  For judgment is without mercy to one who has shown no mercy. Mercy triumphs over judgment.
