God has chosen the Church to be His people in the world. He has bestowed on them a special status and made them to be a set apart people. He has done this out of His own kindness and mercy through the gospel. The Church is to glorify him through worship and tell of His goodness to the world as a result of His kindness and mercy toward them in Christ. A people who were once not a people are now the people of God because of the Cross.
