1 John 5:6-13 - The Certainty Of God's Testimony

6 This is he that came by water and blood, even Jesus Christ; not by water only, but by water and blood. And it is the Spirit that beareth testimony, because the Spirit is truth. 7 For there are three that bear testimony in heaven, the Father, the Word, and the Holy Spirit, and these three are one. 8 And there are three that bear testimony on earth, the spirit, and the water, and the blood: and these three agree in one. 9 If we receive the testimony of men, the testimony of God is greater: for this is the testimony 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 hath not believed the testimony that God gave of his Son. 11 And this is the testimony, that God hath given to us eternal life: and this life is in his Son.

12 He that hath the Son, hath life; and he that hath not the Son of God, hath not life. 13 These things have I written to you that believe on the name of the Son of God; that ye may know that ye have eternal life, and that ye may believe on the name of the Son of God.
