Are children of God and the children of the devil brothers and sister to each other? 1 John, Chapter 3 7:Little children, let no man deceive you: he that doeth righteousness is righteous, even as he is righteous. 8:He that committeth sin is of the devil; for the devil sinneth from the beginning. For this purpose the Son of God was manifested, that he might destroy the works of the devil. 9:Whosoever is born of God doth not commit sin; for his seed remaineth in him: and he cannot sin, because he is born of God. 10:In this the children of God are manifest, and the children of the devil: whosoever doeth not righteousness is not of God, neither he that loveth not his brother.
