1 John 3:10 (KJV)

And ye know that he was manifested to take away our sins; and in him is no sin.

Whosoever abideth in him sinneth not: whosoever sinneth hath not seen him, neither known him.

Little children, let no man deceive you: he that doeth righteousness is righteous, even as he is righteous.

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.

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.

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

Not as Cain, who was of that wicked one, and slew his brother. And wherefore slew he him? Because his own works were evil, and his brother's righteous.

Marvel not, my brethren, if the world hate you.

We know that we have passed from death unto life, because we love the brethren. He that loveth not his brother abideth in death.

Whosoever hateth his brother is a murderer: and ye know that no murderer hath eternal life abiding in him.
