Certainly the horizon of the reign of God is immeasurable; God's revolution also eliminates death and leads in the end to an eternal life with God. But it begins here, on this earth, and it is about this world because from the very beginning God's intent was nothing other than the world. From that point of view the "world" of resurrection can be nothing other than the perfected, healed and sanctified world in which we now live. To misuse or deny this is to slander Jesus' message and corrupt it.
