1 St John 3:7-10

Little children, let no man deceive you. He that doth justice is just, even as he is just. He that committeth sin is of the devil: for the devil sinneth from the beginning. For this purpose, the Son of God appeared, that he might destroy the works of the devil. Whosoever is born of God, committeth not sin: for his seed abideth in him, and he can not sin, because he is born of God. In this the children of God are manifest, and the children of the devil. Whosoever is not just, is not of God, nor he that loveth not his brother.
