God’s plan is to establish His kingdom through the preaching of the cross. His purpose is to rule in the hearts of His people. The progress of this spiritual kingdom will be steady, but slow. In one sense, the kingdom has already come with the death and resurrection of Jesus Christ. It continues to grow as His cross and His empty tomb are preached in all the world. There is another sense, however, in which we are still looking for the kingdom, waiting for the King to come again. We live in the kingdom of grace, where Christ rules by faith, but we wait for the kingdom of glory, when Christ will reign supreme over all.
