John 14:15-18

15 "If ye love me, keep my commandments."
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."
18 "I will not leave you comfortless: I will come to you."
