13 I have written these things to you who believe in the name of the Son of God so that you may know that you have eternal life. 14 And this is the confidence that we have before him: that whenever we ask anything according to his will, he hears us. 15 And if we know that he hears us in regard to whatever we ask, then we know that we have the requests that we have asked from him. 16 If anyone sees his fellow Christian committing a sin not resulting in death, he should ask, and God will grant life to the person who commits a sin not resulting in death. There is a sin resulting in death. I do not say that he should ask about that. 17 All unrighteousness is sin, but there is sin not resulting in death. 18 We know that everyone fathered by God does not sin, but God protects the one he has fathered, and the evil one cannot touch him. 19 We know that we are from God, and the whole world lies in the power of the evil one. 20 And we know that the Son of God has come and has given us insight to know him who is true, and we are in him who is true, in his Son Jesus Christ. This one is the true God and eternal life. 21 Little children, guard yourselves from idols.
