6 This is hee that came by water and blood, euen Iesus Christ, not by water onely, but by water and blood: and it is the Spirit that beareth witnesse, because the Spirit is trueth.
7 For there are three that beare record in heauen, the Father, the Word, and the holy Ghost: and these three are one.
8 And there are three that beare witnesse in earth, the Spirit, and the Water, and the Blood, and these three agree in one.
9 If we receiue the witnesse of men, the witnesse of God is greater: for this is the witnesse of God, which hee hath testified of his Sonne.
10 Hee that beleeueth on the Sonne of God, hath the witnesse in himselfe: he that beleeueth not God, hath made him a liar, because he beleeueth not the record that God gaue of his Sonne.
11 And this is the record, that God hath giuen to vs eternall life, and this life is in his Sonne.
12 Hee that hath the Sonne, hath life; and hee that hath not the Sonne, hath not life.
