The gospel is boldly advancing under the contested reign and inevitable victory of Jesus the king. This side of Jesus' death and resurrection, all of God's sovereignty is mediated exclusively through King Jesus. . . . Christ “must reign until he has put all his enemies under his feet” ([I Cor.] 15:25). That presupposes the reign is still contested, and still advances. This is of a piece with Jesus' claim, “I will build my church, and the gates of hell shall not prevail against it” (Matt 16:18). But one day, the final enemy, death itself, will die, and Jesus' mediatorial kingship will end. God will be all in all.
