Passage
if, indeed, ye did hear of the dispensation of the grace of God that was given to me in regard to you,
if, indeed, ye did hear of the dispensation of the grace of God that was given to me in regard to you,
Ephesians 3:1 For this cause, I Paul, the prisoner of Christ Jesus for you the nations,
Ephesians 3:2 if, indeed, ye did hear of the dispensation of the grace of God that was given to me in regard to you,
Ephesians 3:3 that by revelation He made known to me the secret, according as I wrote before in few <FI>words<Fi> --
Ephesians 3:4 in regard to which ye are able, reading <FI>it<Fi> , to understand my knowledge in the secret of the Christ,
The verse centers on "grace", "indeed", "hear", "dispensation", "given", and "regard". It is saying that the verse draws attention to "grace" and "indeed", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 1's "For this cause I Paul the prisoner..." into verse 3's "that by revelation He made known to...", so "grace" and "indeed" 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 "grace" and "indeed" with trust shaped by these words, not by a vague optimism outside the passage.
