1st John Chapter 5 Darby English Bible
He that believes on the Son of God has the witness in himself; he that does not believe God has made him a liar, because he has not believed in the witness which God has witnessed concerning his Son.
If any one see his brother sinning a sin not unto death, he shall ask, and he shall give him life, for those that do not sin unto death. There is a sin to death: I do not say of that that he should make a request.
And we know that the Son of God has come, and has given us an understanding that we should know him that [is] true; and we are in him that [is] true, in his Son Jesus Christ. He is the true God and eternal life.
