'Spirit of Truth' in the Bible

even the spirit of truth, whom the world cannot receive, because it neither sees nor knows him: but ye shall know him, for he shall dwell with you, and shall be in you.

but when the advocate is come, whom I will send to you from the father, even the spirit of truth, which proceedeth from the father, he shall testify of me.

but when he, the spirit of truth shall come, he will inform you of all those truths: for he will not speak from himself; but the information he shall receive will he communicate: and acquaint you with what is to come.

we are of God: he that knoweth God, heareth us; he that is not of God, heareth not us. by this we distinguish the spirit of truth from the spirit of imposture.
