1 João 5.6-10

⁶ This is he who came by water and blood, even Jesus Christ; not by water only, but by water and blood. And it is the Spirit that testifies, because the Spirit is the truth. ⁷ For there are three that testify in heaven: the Father, the Word, and the Holy Spirit; and these three are one. ⁸ And there are three that testify on earth: the Spirit, the water, and the blood; and these three agree as one. ⁹ If we receive the testimony of men, the testimony of God is greater; for this is the testimony of God which He has testified of His Son. ¹⁰ He who believes in the Son of God has the testimony in himself; he who does not believe God has made Him a liar, because he has not believed the testimony that God has given of His Son.
