SUMMARY: In this sermon, we explored Ephesians 4:12-16 and the central theme of maturity within the church. We began by asking why unity, diversity, and theology matter, and discovered that the answer is maturity—growing up together as the body of Christ. Maturity is not just about personal growth but about being equipped, building up others, and engaging in the real “game” of faith outside the church walls. We discussed the importance of being knowledgeable about Jesus, developing stability in our faith, and ensuring that every member is both connected and contributing. The ultimate goal is a church where each person finds their place, serves with purpose, and grows together into the fullness of Christ.
