Passage
*I*, the prisoner in [the] Lord, exhort you therefore to walk worthy of the calling wherewith ye have been called,
*I*, the prisoner in [the] Lord, exhort you therefore to walk worthy of the calling wherewith ye have been called,
Ephesians 4:1 *I*, the prisoner in [the] Lord, exhort you therefore to walk worthy of the calling wherewith ye have been called,
Ephesians 4:2 with all lowliness and meekness, with long-suffering, bearing with one another in love;
Ephesians 4:3 using diligence to keep the unity of the Spirit in the uniting bond of peace.
The verse centers on "called", "prisoner", "lord", "exhort", "therefore", "walk", "worthy", and "calling". It is saying that the verse draws attention to "called" and "prisoner", so its meaning should be read from those terms before moving to application.
The next verse adds "with all lowliness and meekness with long-suffering...", so "called" and "prisoner" should be read forward into that movement. 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 "called" and "prisoner" with trust shaped by these words, not by a vague optimism outside the passage.
