James 2:10-13

For whosoever shall keep the whole law, and yet stumble in one point, he is become guilty of all. For he that said, Do not commit adultery, said also, Do not kill. Now if thou dost not commit adultery, but killest, thou art become a transgressor of the law. So speak ye, and so do, as men that are to be judged by a law of liberty. For judgment is without mercy to him that hath showed no mercy: mercy glorieth against judgment.
