John 14:16; John 14:26; John 15:26; John 16:7
And I will pray the Father, and he shall give you another Comforter, that he may abide with you for ever;
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.
But when the Comforter is come , whom I will send unto you from the Father, even the Spirit of truth, which proceedeth from the Father, he shall testify of me:
Nevertheless I tell you the truth; It is expedient for you that I go away : for if I go not away , the Comforter will not come unto you; but if I depart , I will send him unto you.
