1Jn 3:9-10 KJV
(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.
You had better not sin.
