1 John 5:7-9

American Standard Version

⁷ And it is the Spirit that beareth witness, because the Spirit is the truth. ⁸ For there are three who bear witness, the Spirit, and the water, and the blood: and the three agree in one. ⁹ If we receive the witness of men, the witness of God is greater: for the witness of God is this, that he hath borne witness concerning his Son.
