1 John 5:1, 6, 11-13

Everyone who believes that Jesus is the Messiah has been born of God, and everyone who loves the Father also loves the one born of Him.

Jesus Christ — He is the One who came by water and blood, not by water only, but by water and by blood. And the Spirit is the One who testifies, because the Spirit is the truth.

And this is the testimony: God has given us eternal life, and this life is in His Son. The one who has the Son has life. The one who doesn’t have the Son of God does not have life. I have written these things to you who believe in the name of the Son of God, so that you may know that you have eternal life.
