Passage
that ye may be in strength to comprehend, with all the saints, what <FI>is<Fi> the breadth, and length, and depth, and height,
that ye may be in strength to comprehend, with all the saints, what <FI>is<Fi> the breadth, and length, and depth, and height,
Ephesians 3:16 that He may give to you, according to the riches of His glory, with might to be strengthened through His Spirit, in regard to the inner man,
Ephesians 3:17 that the Christ may dwell through the faith in your hearts, in love having been rooted and founded,
Ephesians 3:18 that ye may be in strength to comprehend, with all the saints, what <FI>is<Fi> the breadth, and length, and depth, and height,
Ephesians 3:19 to know also the love of the Christ that is exceeding the knowledge, that ye may be filled--to all the fulness of God;
Ephesians 3:20 and to Him who is able above all things to do exceeding abundantly what we ask or think, according to the power that is working in us,
The verse centers on "strength", "comprehend", "saints", "breadth", "length", "depth", and "height". It is saying that the verse draws attention to "strength" and "comprehend", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 17's "that the Christ may dwell through the..." into verse 19's "to know also the love of the...", so "strength" and "comprehend" belong inside that flow. In Ephesians context, the local focus is grace, union with Christ, the church, and new creation.
A plain takeaway is to answer the verse's own emphasis on "strength" and "comprehend" with trust shaped by these words, not by a vague optimism outside the passage.
