But the Comforter, which is the Holy Ghost, whom the Father
will send in my name, he shall teach you all things, and bring all
things to your remembrance, whatsoever I have said unto you.
-- John 14:26
I have yet many things to say unto you, but ye cannot bear them now. Howbeit when he, the Spirit of truth, is come, he will guide you into
all truth: for he shall not speak of himself; but whatsoever he shall
hear, that shall he speak: and he will shew you things to come.
-- John 16:12f.
