1 John 5:8-10

King James Version

⁸ And there are three that bear witness in earth, the Spirit, and the water, and the blood: and these three agree in one.

⁹ If we receive the witness of men, the witness of God is greater: for this is the witness of God which he hath testified of his Son.

¹⁰ He that believeth on the Son of God hath the witness in himself: he that believeth not God hath made him a liar; because he believeth not the record that God gave of his Son.
