4. He that says, I know him, and does not keep his commandments, is a liar, and the truth is not in him;
5. but whoever keeps his word, in him verily the love of God is perfected. Hereby we know that we are in him.
6. He that says he abides in him ought, even as he walked, himself also so to walk.
7. Beloved, I write no new commandment to you, but an old commandment, which ye have had from the beginning. The old commandment is the word which ye heard.
8. Again, I write a new commandment to you, which thing is true in him and in you, because the darkness is passing and the true light already shines.
9. He who says he is in the light, and hates his brother, is in the darkness until now.
10. He that loves his brother abides in light, and there is no occasion of stumbling in him.
11. But he that hates his brother is in the darkness, and walks in the darkness, and knows not where he goes, because the darkness has blinded his eyes.
12. I write to you, children, because your sins are forgiven you for his name's sake.
13. I write to you, fathers, because ye have known him that is from the beginning. I write to you, young men, because ye have overcome the wicked one. I write to you, little children, because ye have known the Father.
14. I have written to you, fathers, because ye have known him that is from the beginning. I have written to you, young men, because ye are strong, and the word of God abides in you, and ye have overcome the wicked one.
15. Love not the world, nor the things in the world. If any one love the world, the love of the Father is not in him;
16. because all that is in the world, the lust of the flesh, and the lust of the eyes, and the pride of life, is not of the Father, but is of the world.
17. And the world is passing, and its lust, but he that does the will of God abides for eternity.
