Ephesians 3:17

“That Christ may dwell in your hearts by faith, &c.] This is another petition put up by the apostle for the Ephesians, which is for the inhabitation of Christ in them: the inhabitant Christ is he who dwells in the highest heavens, who dwells in the Father, and the Father in him, in whom all fulness dwells, the fulness of the Godhead, and the fulness of grace; so that those in whose hearts he dwells cannot want any good thing, must be in the greatest safety, and enjoy the greatest comfort and pleasure; and this inhabitation of Christ prayed for is not to be understood in such sense, as he dwells everywhere, being the omnipresent God; or as he dwells in the human nature; nor of his dwelling…”

That ye being rooted - Firmly established - as a tree is whose roots strike deep, and extend afar. The meaning is, that his love should be as firm in our hearts, as a tree is in the soil, whose roots strike deep into the earth. And grounded - θεθεμελιωμένοι tethemeliōmenoi - “founded” - as a building is on a foundation. The word is taken from architecture, where a firm foundation is laid, and the meaning is, that he wished…”

“Dwell - That is, constantly and sensibly abide. Ephesians 3:18”

“3:17 Having Christ . . . make his home in your hearts is the source of spiritual power for life and ministry (see John 14:16-17, 23; 15:4-5; Gal 2:20).”
