4. Every one that practises sin practises also lawlessness; and sin is lawlessness.
5. And ye know that he has been manifested that he might take away our sins; and in him sin is not.
6. Whoever abides in him, does not sin: whoever sins, has not seen him or known him.
7. Children, let no man lead you astray; he that practises righteousness is righteous, even as he is righteous.
8. He that practises sin is of the devil; for from the beginning the devil sins. To this end the Son of God has been manifested, that he might undo the works of the devil.
9. Whoever has been begotten of God does not practise sin, because his seed abides in him, and he cannot sin, because he has been begotten of God.
10. In this are manifest the children of God and the children of the devil. Whoever does not practise righteousness is not of God, and he who does not love his brother.
11. For this is the message which ye have heard from the beginning, that we should love one another:
12. not as Cain was of the wicked one, and slew his brother; and on account of what slew he him? because his works were wicked, and those of his brother righteous.
13. Do not wonder, brethren, if the world hate you.
