John 14:17-21
17Even 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.
18I will not leave you comfortless: I will come to you.
19Yet a little while, and the world seeth me no more; but ye see me: because I live, ye shall live also.
20At that day ye shall know that I am in my Father, and ye in me, and I in you.
21He that hath my commandments, and keepeth them, he it is that loveth me: and he that loveth me shall be loved of my Father, and I will love him, and will manifest myself to him.
(KJV)
