1 Yochanan (1 Jo) 5:5-8

Who does overcome the world if not the person who believes that Yeshua is the Son of God? He is the one who came by means of water and blood, Yeshua the Messiah — not with water only, but with the water and the blood. And the Spirit bears witness, because the Spirit is the truth. There are three witnesses — the Spirit, the water and the blood — and these three are in agreement.
