John 14:16-19

16And I will beg the Father, and he will give you another Comforter, that he may be with you for ever,

17the Spirit of truth, whom the world cannot receive, because it does not see him nor know him; but ye know him, for he abides with you, and shall be in you.

18I will not leave you orphans, I am coming to you.

19Yet a little and the world sees me no longer; but ye see me; because I live ye also shall live.
