'Witness' in the Bible

(For the life was manifested, and we have seen it, and bear witness, and shew unto you that eternal life, which was with the Father, and was manifested unto us;)

He who keeps his laws is in God and God is in him. And the Spirit which he gave us is our witness that he is in us.

And his Spirit which he has given us is the witness that we are in him and he is in us.

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

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

For they that bear witness are three:

And there are three that bear witness in earth, the spirit, and the water, and the blood: and these three agree in one.

If we receive the witness of men, the witness of God is greater: for this is the witness of God which he hath testified of his Son.

He that believeth on the Son of God hath the witness in himself: he that believeth not God hath made him a liar; because he believeth not the record that God gave of his Son.

And this is the witness, that God has given to us eternal life; and this life is in his Son.
