3:14-21 Paul is concerned with the minds of the members of the church and with their picture of God, for you can rise no higher than your highest conception of what You worship!!

language moves from the ground up and out, construction of a living, or temple, something to contain the fullness of God

strengthened in inner man by Spirit, Christ dwelling inside their hearts by faith, for the purpose of being grounded (biologically and structurally)

power to comprehend corporately (with all the saints) the amount of room needed (i.e. hold a high and unlimited picture of God) and to comprehend the extent of Christ's love (which is beyond comprehending) (Why is it important to know the height width and depth and breadth of something?)

so that You all may be filled with all the fullness of God! If the picture of God all of you have is too small, you won't be able to be a dwelling place for the fullness of God. (Similar to manifold--many colored--If you don't have an appreciation for the many sides of God's wisdom, you won't become a reflection of those many facets! The more your mind comes to appreciate the incomprehensibility of God's greatness, the better you are suited to being a reflection of it.)
