A Small Bit of Commentary

Verse 17 - To “dwell” does not mean to simply visit for a while, but to be at home or set up camp. Has Christ set up camp in your heart? He inhabits your heart not by your good deeds, but by your faith which results in obedience.
With Christ at home in your heart, you are “rooted” on the Rock, where all other ground is sinking sand. When tough times come, only the foundation of the Rock can pull you through.

Verse 19 - “To be filled” - or to have “your whole happy nature flooded” God wants to open up the floodgates of Heaven to pour out into your life. In order to receive this blessing, you as a vessel must be ready to receive it. Have open hands before the Lord to receive the blessing He wants to give according “his power that is at work within us” (verse 20)

Verse 20 - It’s almost like Paul is trying to sum up the vastness of who God is and what He does for His children, but decides that the only way to do such a task is to allude to His omnipotence (all-powerful), His ability to do “immeasurably more” than whatever could ever flow through our imagination.
God is “…able to do superabundantly above the greatest abundance.” - Adam Clarke
Not only is God able, He is willing according to “his power that is at work within us”, or according to His will, which is “good, pleasing, and perfect” (Romans 12:2) For His willingness, see 1 Corinthians 2:9 - He’s already prepared, so He is willing to fulfill what He’s prepared.
