James 2
The Sin of Partiality
1My brethren, do not hold your faith in our glorious Lord Jesus Christ with an attitude of personal favoritism.
2For if a man comes into your assembly with a gold ring and dressed in fine clothes, and there also comes in a poor man in dirty clothes,
3and you pay special attention to the one who is wearing the fine clothes, and say, "You sit here in a good place," and you say to the poor man, "You stand over there, or sit down by my footstool,"
4have you not made distinctions among yourselves, and become judges with evil motives?
5Listen, my beloved brethren: did not God choose the poor of this world to be rich in faith and heirs of the kingdom which He promised to those who love Him?
6But you have dishonored the poor man. Is it not the rich who oppress you and personally drag you into court?
7Do they not blaspheme the fair name by which you have been called?
8If, however, you are fulfilling the royal law according to the Scripture, "YOU SHALL LOVE YOUR NEIGHBOR AS YOURSELF," you are doing well.
9But if you show partiality, you are committing sin and are convicted by the law as transgressors.
10For whoever keeps the whole law and yet stumbles in one point, he has become guilty of all.
11For He who said, "DO NOT COMMIT ADULTERY," also said, "DO NOT COMMIT MURDER." Now if you do not commit adultery, but do commit murder, you have become a transgressor of the law.
12So speak and so act as those who are to be judged by the law of liberty.
13For judgment will be merciless to one who has shown no mercy; mercy triumphs over judgment.
