Ephesians 4:1 - Ellicott's Commentary On The Whole Bible

Worthy of the vocation wherewith ye are called. — This “being worthy of the Christian calling” may obviously show itself in any of the graces of regenerate humanity, all being features of the image of Christ. Thus in 1 Peter 1:15 it expresses itself in “holiness” (as in the frequent phrase “called to be saints”); in Philippians 1:27-30, in steadfastness of faith. But in this passage the especial point which has been dwelt upon in their calling is the fact that they were aliens, helpless and miserable, and that they are now united in one body with the ancient people of God. Hence, naturally, the graces declared to correspond with their calling, so viewed, are the graces of humility and gentleness, teaching them to sink all thought of self in “the unity of the Spirit.”
