The Holy Spirit

John 14
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.

The Holy Spirit can pass by you, like a warm breeze. The Holy Spirit can, from time to time, fill you. The Holy Spirit can dwell in you.

I remember the day that I first knew that the Holy Spirit "shall be in you."
