Ephesians 3:17

May dwell [κ α τ ο ι κ η σ α ι]. Settle down and abide. Take up His permanent abode, so that ye may be a habitation [κ α τ ο ι κ η τ η ρ ι ο ν] of God. See on ch. Ephesians 2:22. The connection is with the preceding clause : " to be strengthened, etc., so that Christ may dwell, the latter words having at once a climactic and an explanatory force, and adding the idea of permanency to that of strengthening.

By faith [δ ι α τ η ς π ι σ τ ε ω ς]. Through your (the article) faith, as the medium of appropriating Christ. Faith opens the door and receives Him who knocks. Revelation 3:20.
