1 John 5:13-21 New Revised Standard Version (NRSV)
13 I write 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 boldness we have in him, that if we ask anything according to his will, he hears us. 15 And if we know that he hears us in whatever we ask, we know that we have obtained the requests made of him. 16 If you see your brother or sister[a] committing what is not a mortal sin, you will ask, and God[b] will give life to such a one—to those whose sin is not mortal. There is sin that is mortal; I do not say that you should pray about that. 17 All wrongdoing is sin, but there is sin that is not mortal.
18 We know that those who are born of God do not sin, but the one who was born of God protects them, and the evil one does not touch them. 19 We know that we are God’s children, and that the whole world lies under the power of the evil one. 20 And we know that the Son of God has come and has given us understanding so that we may know him who is true;[c] and we are in him who is true, in his Son Jesus Christ. He is the true God and eternal life.
21 Little children, keep yourselves from idols.[d]
