what we have seen and heard
we also declare to you,
so that you may have fellowship along with us;
and indeed our fellowship is with the Father
and with His Son Jesus Christ.

But if we walk in the light as He Himself is in the light, we have fellowship with one another, and the blood of Jesus His Son cleanses us from all sin.

My little children, I am writing you these things so that you may not sin. But if anyone does sin, we have an advocate with the Father—Jesus Christ the Righteous One.

Who is the liar, if not the one who denies that Jesus is the Messiah? This one is the antichrist: the one who denies the Father and the Son.

Now this is His command: that we believe in the name of His Son Jesus Christ, and love one another as He commanded us.

This is how you know the Spirit of God: Every spirit who confesses that Jesus Christ has come in the flesh is from God.

But every spirit who does not confess Jesus is not from God. This is the spirit of the antichrist; you have heard that he is coming, and he is already in the world now.

Whoever confesses that Jesus is the Son of God—God remains in him and he in God.

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.

And who is the one who conquers the world but the one who believes that Jesus is the Son of God?

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 we know that the Son of God has come and has given us understanding so that we may know the true One. We are in the true One—that is, in His Son Jesus Christ. He is the true God and eternal life.
