In this keynote message from TGC25, Alistair Begg unpacks Ephesians 3:1–13, showing how Paul’s suffering and calling reveal the mystery of Christ—that the church is God’s new, unified, multicultural people. Begg contrasts the world’s longing for peace with God’s eternal plan to unite all things in Christ, making the church a powerful display of his wisdom. Begg urges listeners to reject isolation and individualism and instead embrace the beauty of the gospel, the church’s purpose, and the hope of glory through Christ.
