James 2:13-25

For judgment is without mercy to him that hath showed no mercy: mercy glorieth against judgment. What doth it profit, my brethren, if a man say he hath faith, but have not works? can that faith save him? If a brother or sister be naked and in lack of daily food, and one of you say unto them, Go in peace, be ye warmed and filled; and yet ye give them not the things needful to the body; what doth it profit? Even so faith, if it have not works, is dead in itself. Yea, a man will say, Thou hast faith, and I have works: show me thy faith apart from thy works, and I by my works will show thee my faith. Thou believest that God is one; thou doest well: the demons also believe, and shudder. But wilt thou know, O vain man, that faith apart from works is barren? Was not Abraham our father justified by works, in that he offered up Isaac his son upon the altar? Thou seest that faith wrought with his works, and by works was faith made perfect; and the scripture was fulfilled which saith, And Abraham believed God, and it was reckoned unto him for righteousness; and he was called the friend of God. Ye see that by works a man is justified, and not only by faith. And in like manner was not also Rahab the harlot justified by works, in that she received the messengers, and sent them out another way?
