"For this reason I bow my knees to the Father of our Lord Jesus Christ, from whom the whole family in heaven and earth is named, that He would grant you, according to the riches of His glory, to be strengthened with might through His Spirit in the inner man, that Christ may dwell in your hearts through faith; that you, being rooted and grounded in love, may be able to comprehend with all the saints what is the width and length and depth and height-to know the love of Christ which passes knowledge; that you may be filled with all the fullness of God. Now to Him who is able to do exceedingly abundantly above all that we ask or thing, according to the power that workds in us, to Him be glory in the church by Christ Jesus to all generations, forever and ever. Amen." - Ephesians 3:14-21 (NKJV)
At the foundation, Paul is desperate for one thing: that every part of God would come to live in every part of us, to be totally filled up by God's presence without friction or empty space. This makes the first line imperative: "I bow my knees to the Father." The way to be filled with God is to be emptied of self. The way to receive His strength is to lay down our own. The more we daily surrender our live, the more fully we come to experience His.
