MSB(i)
7 For there are three that testify:
8 the Spirit, the water, and the blood—and these three are in agreement.
9 Even if we accept human testimony, the testimony of God is greater. For this is the testimony that God has given about His Son.
10 Whoever believes in the Son of God has this testimony within him; whoever does not believe God has made Him out to be a liar, because he has not believed in the testimony that God has given about His Son.
11 And this is that testimony: God has given us eternal life, and this life is in His Son.
