[So] that in Him in every respect you were enriched, in full power and readiness of speech [to speak of your faith] and complete knowledge and illumination [to give you full insight into its meaning].
1st Corinthians 1:5 [AMP]
16 May He grant you out of the rich treasury of His glory to be strengthened and reinforced with mighty power in the inner man by the [Holy] Spirit [Himself indwelling your innermost being and personality].
17 May Christ through your faith [actually] dwell (settle down, abide, make His permanent home) in your hearts! May you be rooted deep in love and founded securely on love,
18 That you may have the power and be strong to apprehend and grasp with all the saints [God's devoted people, the experience of that love] what is the breadth and length and height and depth [of it];
19 [That you may really come] to know [practically, through experience for yourselves] the love of Christ, which far surpasses mere knowledge [without experience]; that you may be filled [through all your being] unto all the fullness of God [may have the richest measure of the divine Presence, and become a body wholly filled and flooded with God Himself]!
Ephesians 3:16-19 [AMP]
