4. Whosoever commits sin transgresses also the law: for sin is the transgression of the law.
5. And you know that he was manifested to take away our sins; and in him is no sin.
6. Whosoever abides in him sins not: whosoever sins has not seen him, neither known him.
7. Little children, let no man deceive you: he that does righteousness is righteous, even as he 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 was manifested, that he might destroy the works of the devil.
9. Whosoever is born of God does not commit sin; for his nature remains 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 does not righteousness is not of God, neither he that loves not his brother.
11. For this is the message that you heard from the beginning, that we should love one another.
12. Not as Cain, who was of that wicked one, and slew his brother. And why slew he him? Because his own works were evil, and his brother's righteous.
13. Marvel not, my brethren, if the world hates you.
14. We know that we have passed from death unto life, because we love the brethren. He that loves not his brother abides in death.
15. Whosoever hates his brother is a murderer: and you know that no murderer has eternal life abiding in him.
16. By this perceive we the love of God, because he laid down his life for us: and we ought to lay down our lives for the brethren.
17. But whoever has this world's goods, and sees his brother have need, and shuts up his heart of compassion from him, how dwells the love of God in him?
18. My little children, let us not love in word, neither in tongue; but in deed and in truth.
19. And by this we know that we are of the truth, and shall assure our hearts before him.
20. For if our heart condemns us, God is greater than our heart, and knows all things.
