James asks the brothers not to hold the faith in our glorious Lord Jesus Christ with partiality. If a man with a gold ring and fine clothing comes into the assembly and a poor man in shabby clothing also comes in, and they pay attention to the rich man and tell the poor man to stand or sit on the floor, they have made distinctions and become judges with evil thoughts. God chose the poor of this world to be rich in faith and heirs of the kingdom, while the rich oppress them and blaspheme the honorable name by which they were called.
If they fulfill the royal law according to Scripture, you shall love your neighbor as yourself, they do well; but if they show partiality, they commit sin. Whoever keeps the whole law but fails in one point has become accountable for all of it, for the one who said do not commit adultery also said do not murder. Speak and act as those judged under the law of liberty, for judgment is without mercy to the one who has shown no mercy; mercy triumphs over judgment.
The second half asks: what good is it if someone says he has faith but does not have works? Can that faith save him? If a brother or sister is poorly clothed and lacking daily food, and one of you says go in peace, be warmed and filled, without giving them what the body needs, what good is that? So also faith by itself, if it does not have works, is dead. Even the demons believe and shudder.
Abraham was justified by works when he offered his son Isaac on the altar; his faith was active along with his works and was completed by them, and the Scripture was fulfilled that says he believed God and it was counted to him as righteousness, and he was called a friend of God. In the same way Rahab the prostitute was justified by works when she received the messengers and sent them out by another way. As the body apart from the spirit is dead, so also faith apart from works is dead.
