1 John 3:9-11

9 Whoever 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: whoever doeth not righteousness is not of God, neither he that loveth not his brother.

11 For this is the message that ye have heard from the beginning, that we should love one another.
