This is how we know that we live in him and he in us: He has given us of his Spirit.

And we have seen and testify that the Father has sent his Son to be the Savior of the world.

If anyone acknowledges that Jesus is the Son of God, God lives in them and they in God.

And so we know and rely on the love God has for us. God is love. Whoever lives in love lives in God, and God in them.

This is how love is made complete among us so that we will have confidence on the day of judgment: In this world we are like Jesus.

Whoever claims to love God yet hates a brother or sister is a liar. For whoever does not love their brother and sister, whom they have seen, cannot love God, whom they have not seen.

And he has given us this command: Anyone who loves God must also love their brother and sister.

Faith in the Incarnate Son of God

Everyone who believes that Jesus is the Christ is born of God, and everyone who loves the father loves his child as well.

Who is it that overcomes the world? Only the one who believes that Jesus is the Son of God.

This is the one who came by water and blood—Jesus Christ. He did not come by water only, but by water and blood. And it is the Spirit who testifies, because the Spirit is the truth.

the Spirit, the water and the blood; and the three are in agreement.

We accept human testimony, but God’s testimony is greater because it is the testimony of God, which he has given about his Son.

Whoever believes in the Son of God accepts this testimony. Whoever does not believe God has made him out to be a liar, because they have not believed the testimony God has given about his Son.

And this is the testimony: God has given us eternal life, and this life is in his Son.

Whoever has the Son has life; whoever does not have the Son of God does not have life.
