Paul's letter to the church of Ephesus is a celebration of the new identity of the believer and the power of the Gospel to change everything about all people. After celebrating the truths of the new birth, Paul lays out the conduct expected of the believer in their church, the world, their homes, and their workplaces that ought to be an outflow of these truths. Paul's message: "Praise God, this is who you are; now go BE who you are."
