James 2:8–13 (ESV)
[8] If you really fulfill the royal law according to the Scripture, “You shall love your neighbor as yourself,” you are doing well. [9] But if you show partiality, you are committing sin and are convicted by the law as transgressors. [10] For whoever keeps the whole law but fails in one point has become guilty of all of it. [11] 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. [12] So speak and so act as those who are to be judged under the law of liberty. [13] For judgment is without mercy to one who has shown no mercy. Mercy triumphs over judgment.
