Passage
If ye haue heard of the dispensation of the grace of God, which is giuen me to you warde,
If ye haue heard of the dispensation of the grace of God, which is giuen me to you warde,
Ephesians 3:1 For this cause, I Paul am the prisoner of Iesus Christ for you Gentiles,
Ephesians 3:2 If ye haue heard of the dispensation of the grace of God, which is giuen me to you warde,
Ephesians 3:3 That is, that God by reuelation hath shewed this mysterie vnto me (as I wrote aboue in fewe wordes,
Ephesians 3:4 Whereby when ye reade, ye may knowe mine vnderstanding in the mysterie of Christ)
The verse centers on "grace", "haue", "heard", "dispensation", "giuen", and "warde". It is saying that the verse draws attention to "grace" and "haue", 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 am the..." into verse 3's "That is that God by reuelation hath...", so "grace" and "haue" 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 "haue" with trust shaped by these words, not by a vague optimism outside the passage.
