'Spirit' in the Bible

And he that keeps his commandments abides in him, and he in him. And hereby we know that he abides in us, by the Spirit which he has given to us.

Beloved, believe not every spirit, but prove the spirits, if they are of God; because many false prophets are gone out into the world.

and every spirit which does not confess Jesus Christ come in flesh is not of God: and this is that power of the antichrist, of which ye have heard that it comes, and now it is already in the world.

We are of God; he that knows God hears us; he who is not of God does not hear us. From this we know the spirit of truth and the spirit of error.

Hereby we know that we abide in him and he in us, that he has given to us of his Spirit.

This is he that came by water and blood, Jesus the Christ; not by water only, but by water and blood. And it is the Spirit that bears witness, for the Spirit is the truth.

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