The Pleasure of God in His Fame

The aim of missions is to bring about the obedience of faith among all the unreached peoples of the world. But that is not the ultimate goal. The ultimate goal —even of faith and obedience—is “for the sake of his name” (Romans 1:5). The fame of Christ, the reputation of Christ, is what burned in the heart of the apostle Paul. The faith of the nations was not an end in itself. It was the way that the name of Christ would be honored.
