Brad Dufault concludes his Ephesians 4 series by examining verse 16's teaching that "each part does its work," emphasizing that every believer has a necessary role in the body of Christ. He addresses common objections—feeling too different, limited by circumstances, or lacking qualifications—by arguing that these very factors define (not diminish) each person's contribution to the body. Dufault uses Paul's imprisonment as an example: what seemed like an obstacle to ministry became the context for writing Ephesians itself, showing how God sovereignly uses our circumstances, backgrounds, and differences to build up the church in both quantity and quality.
