Passage
Now unto him that is able to do exceeding abundantly above all that we ask or think, according to the power that worketh in us,
Now unto him that is able to do exceeding abundantly above all that we ask or think, according to the power that worketh in us,
Ephesians 3:18 may be strong to apprehend with all the saints what is the breadth and length and height and depth,
Ephesians 3:19 and to know the love of Christ which passeth knowledge, that ye may be filled unto all the fulness of God.
Ephesians 3:20 Now unto him that is able to do exceeding abundantly above all that we ask or think, according to the power that worketh in us,
Ephesians 3:21 unto him [be] the glory in the church and in Christ Jesus unto all generations for ever and ever. Amen.
The verse centers on "able", "exceeding", "abundantly", "above", "think", "power", and "worketh". It is saying that the verse draws attention to "able" and "exceeding", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 19's "and to know the love of Christ..." into verse 21's "unto him be the glory in the...", so "able" and "exceeding" 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 "able" and "exceeding" with trust shaped by these words, not by a vague optimism outside the passage.
