Heres'a great thought from Tozer:
To know the love of Christ which passes knowledge; that you may be filled with all the fullness of God. --Ephesians 3:19
Pentecost means that the Deity came to mankind to give Himself to man, that man might breathe Him in as he breathes in the air, that He might fill men. Dr. A. B. Simpson used an illustration which was about as good as any I ever heard. He said, "Being filled with the fullness of God is like a bottle in the ocean. You take the cork out of the bottle and sink it in the ocean, and you have the bottle completely full of ocean. The bottle is in the ocean, and the ocean is in the bottle. The ocean contains the bottle, but the bottle contains only a little bit of the ocean. So it is with the Christian."
We are filled unto the fullness of God, but, of course, we cannot contain all of God because God contains us; but we can have all of God that we can contain. If we only knew it, we could enlarge our vessel. The vessel gets bigger as we go on with God. The Counselor, 68.
