9. If we receive the witness of men, the witness of God is greater. For this is the witness of God which he has witnessed concerning his Son.
10. He that believes on the Son of God has the witness in himself; he that does not believe God has made him a liar, because he has not believed in the witness which God has witnessed concerning his Son.
11. And this is the witness, that God has given to us eternal life; and this life is in his Son.
12. He that has the Son has life: he that has not the Son of God has not life.
13. These things have I written to you that ye may know that ye have eternal life who believe on the name of the Son of God.
14. And this is the boldness which we have towards him, that if we ask him anything according to his will he hears us.
15. And if we know that he hears us, whatsoever we ask, we know that we have the petitions which we have asked of him.
16. If any one see his brother sinning a sin not unto death, he shall ask, and he shall give him life, for those that do not sin unto death. There is a sin to death: I do not say of that that he should make a request.
17. Every unrighteousness is sin; and there is a sin not to death.
18. We know that every one begotten of God does not sin, but he that has been begotten of God keeps himself, and the wicked one does not touch him.
19. We know that we are of God, and the whole world lies in the wicked one.
20. And we know that the Son of God has come, and has given us an understanding that we should know him that is true; and we are in him that is true, in his Son Jesus Christ. He is the true God and eternal life.
21. Children, keep yourselves from idols.
