'Spirit' in the Bible

He who keeps his commandments remains in him, and he in him. By this we know that he remains in us, by the Spirit which he gave us.

Beloved, don't believe every spirit, but test the spirits, whether they are of God, because many false prophets have gone out into the world.

By this you know the Spirit of God: every spirit who confesses that Jesus Christ has come in the flesh is of God,

and every spirit who doesn't confess that Jesus Christ has come in the flesh is not of God, and this is the spirit of the Antichrist, of whom you have heard that it comes. Now it is in the world already.

We are of God. He who knows God listens to us. He who is not of God doesn't listen to us. By this we know the spirit of truth, and the spirit of error.

By this we know that we remain in him and he in us, because he has given us of his Spirit.

This is he who came by water and blood, Jesus Christ; not with the water only, but with the water and the blood. It is the Spirit who testifies, because the Spirit is the truth.

the Spirit, the water, and the blood; and the three agree as one.
