To everyone who has ears to hear, let them hear:
When read carefully, none of the biblical apocalypses, from Ezekiel through Daniel to Mark 13 and John of Patmos, is about either pie in the sky or the Russians in Mesopotamia. They are about how the crucified Jesus is a more adequate key to understanding what God is about in the real world of empires and armies and markets than is the ruler in Rome, with all his supporting military, commercial, and sacerdotal networks.
Then to follow Jesus does not mean renouncing effectiveness. It does not mean sacrificing concern for liberation within the social process in favor of delayed gratification in heaven, or abandoning efficacy in favor of purity. It means that in Jesus we have a clue to which kinds of causation, which kinds of community-building, which kinds of conflict management, go with the grain of the cosmos, of which we know, as Caesar does not, that Jesus is both the Word (the inner logic of things) and the Lord (“sitting at the right hand”). It is not that we begin with a mechanistic universe and then look for cracks and chinks where a little creative freedom might sneak in (for which we would then give God credit): it is that we confess the deterministic world to be enclosed within, smaller than, the sovereignty of the God of the Resurrection and Ascension. “He’s got the whole world in his hands” is a post-ascension testimony. The difference it makes for political behavior is more than merely poetic or motivational.
