This is He who came through water and blood, Jesus Christ, not by water only, but by the water and blood. And the Spirit is He who bears witness, because the Spirit is the truth.
He who believes on the Son of God has the witness in himself. He who does not believe God has made Him a liar, because he does not believe the record that God gave of His Son.
I have written these things to you who believe on the name of the Son of God, that you may know that you have everlasting life, and that you may believe on the name of the Son of God.
If anyone sees his brother sin a sin not to death, he shall ask, and He shall give him life for those that do not sin to death. There is a sin to death, I do not say that he shall pray for it.
And we know that the Son of God has come, and He has given us an understanding so that we may know Him who is true. And we are in Him that is true, in His Son Jesus Christ. This is the true God, and the everlasting life.
