1st John Chapter 5 Young's Literal Translation
This one is he who did come through water and blood -- Jesus the Christ, not in the water only, but in the water and the blood; and the Spirit it is that is testifying, because the Spirit is the truth,
He who is believing in the Son of God, hath the testimony in himself; he who is not believing God, a liar hath made Him, because he hath not believed in the testimony that God hath testified concerning His Son;
If any one may see his brother sinning a sin not unto death, he shall ask, and He shall give to him life to those sinning not unto death; there is sin to death, not concerning it do I speak that he may beseech;
and we have known that the Son of God is come, and hath given us a mind, that we may 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 the life age-during!
