1 John 5:13-21Revised Standard Version (RSV)
13 I write this to you who believe in the name of the Son of God, that you may know that you have eternal life. 14 And this is the confidence which 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 any one sees his brother committing what is not a mortal sin, he will ask, and God[a] will give him life for those whose sin is not mortal. There is sin which is mortal; I do not say that one is to pray for that. 17 All wrongdoing is sin, but there is sin which is not mortal.
18 We know that any one born of God does not sin, but He who was born of God keeps him, and the evil one does not touch him.
19 We know that we are of God, and the whole world is in the power of the evil one.
20 And we know that the Son of God has come and has given us understanding, to know him who is true; and we are in him who is true, in his Son Jesus Christ. This is the true God and eternal life. 21 Little children, keep yourselves from idols.
