|John 14:16, 17, 26
16 And I will pray the Father, and he shall give you another Comforter, that he may abide with you for ever;
17 Even the Spirit of truth; whom the world cannot receive, because it seeth him not, neither knoweth him:
but ye know him; for he dwelleth with you, and shall be in you.
26 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.
