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 bears witness, because the Spirit is truth. 7 For there are three that bear witness in heaven, the Father, the Word, and the Holy Spirit: and these three are one. 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 has testified of his Son. 10 He that believes on the Son of God has the witness in himself: he that believes not God has made him a liar; because he believes not the witness that God gave of his Son. 11 And this is the witness, that God has given to us eternal life, and this life is in his Son.

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