1 John 5:15-21 HNV

15 And if we know that he listens to us whatever we ask, we know that we have the petitions which we have asked of him.
16 If anyone sees his brother sinning a sin not leading to death, he shall ask, and God will give him life for those who sin not to death. There is a sin leading to death. I don't say that concerning this he should make a request.
17 All unrighteousness is sin, and there is a sin not leading to death.
18 We know that whoever is born of God doesn't sin, but he who was born of God keeps himself, and the evil one doesn't touch him.
19 We know that we are of God, and the whole world lies in the power of the evil one.
20 We know that the Son of God has come, and has given us an understanding, that we know him who is true, and we are in him who is true, in his Son Yeshua the Messiah. This is the true God, and eternal life.
21 Little children, keep yourselves from idols.
