Who is it that overcomes the world? Only he who believes that Jesus is the Son of God.16
This is the one who came by water and blood2--Jesus Christ. He did not come by water only, but by water and blood. And it is the Spirit who testifies, because the Spirit is the truth.37
For there are three4 that testify:
thea Spirit, the water and the blood; and the three are in agreement.
We accept man's testimony,5 but God's testimony is greater because it is the testimony of God,6 which he has given about his Son.
Anyone who believes in the Son of God has this testimony in his heart.7 Anyone who does not believe God has made him out to be a liar,8 because he has not believed the testimony God has given about his Son.
And this is the testimony: God has given us eternal life,9 and this life is in his Son.1012
He who has the Son has life; he who does not have the Son of God does not have life.11
