In Him Is No Sin!

8 If we say that we have no sin, we deceive ourselves, and the truth is not in us. (1 John 1:8)

10 If we say that we have not sinned, we make him a liar, and his word is not in us. (1 John 1:10)

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. (1 John 3:9)

How can this be?
