1 John 5:6-13 - The Certainty Of God's Testimony
6 it appear'd by the water, and by the blood, who he was, even Jesus the Messiah; not by the water only, but by the water and by the blood: besides, the spirit is a witness too, now the spirit is truth itself. 7 There are three witnesses in heaven, the Father, the Word, and the Holy Ghost: and these three testify the same thing. 8 so that there are three witnesses, the spirit, the water, and the blood: and these three testify the same thing. 9 if we receive the testimony of men, the testimony of God is greater: now this is the testimony, which God has given us of his son. 10 he that believeth on the son of God, hath the testimony of God thereto: he that does not believe God, impeaches his veracity, because he does not believe the testimony that God gave of his son. 11 Now what is testified, is this, that God has given to us eternal life: and this life is by his son.
12 he that receives the son, is intitled to life; and he that does not receive the son of God, has no title to life. 13 these things have I written to you, that you may know that you have eternal life, by your believing on the name of the son of God.
