Passage
There is one body and one Spirit, just as also you were called in one hope of your calling;
There is one body and one Spirit, just as also you were called in one hope of your calling;
Ephesians 4:2 with all humility and gentleness, with patience, bearing with one another in love,
Ephesians 4:3 being diligent to keep the unity of the Spirit in the bond of peace.
Ephesians 4:4 There is one body and one Spirit, just as also you were called in one hope of your calling;
Ephesians 4:5 one Lord, one faith, one baptism;
Ephesians 4:6 one God and Father of all who is over all and through all and in all.
The verse centers on "called", "Spirit", "body", "just", "hope", and "calling". It is saying that the verse draws attention to "called" and "Spirit", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 3's "being diligent to keep the unity of..." into verse 5's "one Lord one faith one baptism...", so "called" and "Spirit" 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 "called" and "Spirit" with trust shaped by these words, not by a vague optimism outside the passage.
