1 John 5:6

6 Jesus Christ is the one who came with the water of his baptism and the blood of his death. He came not only with the water, but with both the water and the blood. And the Spirit himself testifies that this is true, because the Spirit is truth.

1 John 5:6 In-Context

4 because every child of God is able to defeat the world. And we win the victory over the world by means of our faith.
5 Who can defeat the world? Only the person who believes that Jesus is the Son of God.
6 Jesus Christ is the one who came with the water of his baptism and the blood of his death. He came not only with the water, but with both the water and the blood. And the Spirit himself testifies that this is true, because the Spirit is truth.
7 There are three witnesses:
8 the Spirit, the water, and the blood; and all three give the same testimony.
