Fill Up with God
John 17:23 "I in them, and thou in me, that they may be made perfect in one; and that the world may know that thou hast sent me, and hast loved them, as thou hast loved me."
God loves us the same as He loves Jesus. A true revelation of this will quicken our faith and allow us to walk in the fullness of God. God's love is the key that opens the door to everything that God is. "God is love" (1 John 4:8).
God's love is not one-dimensional. There is width, length, depth and height to it, which can only be comprehended through the revelation and knowledge of the Holy Spirit. Those who only have a superficial knowledge of God's love are like a person who looks at a one-dimensional picture of the real thing.
In Ephesians 3:19, Paul prays for us to know the love of God which passes knowledge. How can we know the love of God if it passes knowledge? This sounds like a contradiction. The Greek word that is translated "know" in this verse is GINOSKO, which is a verb expressing experiential knowledge. The Greek word that is translated "knowledge" is GNOSIS, which is a noun denoting the act of knowledge. Simply, Paul is praying that we will experience the love of God which passes mere knowledge of it.
Since a true revelation of God's love makes us full with the fullness of God, then a lack of being full of God must mean that we lack understanding and experience of God's love. The end result of having understanding and experiential knowledge of God's love is that we will be filled with all the fullness of God.
