1 John 5:6-13 - The Certainty Of God's Testimony
6 This is he that came by water and blood, Jesus, the Christ; not by water only, but by water and by blood; and the Spirit is that which testifies, for the Spirit is the truth. 7 For there are three that testify; the Spirit, and the water, and the blood; and the three are one. 8 (Added verse not retained in Sawyer) 9 If we receive the testimony of men, the testimony of God is greater; for this is the testimony of God that he has testified concerning his Son. 10 He that believes on the Son of God has the testimony in himself; he that believes not God has made him a liar, because he has not believed in the testimony which God has testified concerning his Son. 11 And this is the testimony, that God gave us eternal life, and this life is in his Son.
12 He that has the Son has the life; he that has not the Son has not the life. 13 These things have I written to you, that you who believe in the name of the Son of God may know that you have eternal life.
