3 And every one that has this hope in him purifies himself, even as he is pure.
4 Whosoever commits sin transgresses also the law: for sin is the transgression of the law.
5 And ye know that he appeared to take away our sins, and there is no sin in him.
6 Whosoever abides in him does not sin: whosoever sins has not seen him or known him.
7 Little children, let no one deceive you; he that does righteousness is righteous, even as he also is righteous.
8 He that commits sin is of the devil; for the devil sins from the beginning. For this purpose the Son of God appeared, that he might undo the works of the devil.
9 Whosoever is born of God does not commit sin; for his seed remains in him; and he cannot sin, because he is born of God.
