Jesus predicted an imminently coming kingdom which brings catastrophic death, not N. T. Wright's Christendom

gathering tares to be burned

N. T. Wright, here:

Here is the central element: the point about God’s authority is that the whole Bible is about God establishing his kingdom on earth as in heaven, completing (in other words) the project begun but aborted in Genesis 1–3. This is the big story that we must learn how to tell. It isn’t just about how to get saved, with some cosmology bolted onto the side. This is an organic story about God and the world.  God’s authority is exercised not to give his people lots of true information, not even true information about how they get saved (though that comes en route). God’s authority, vested in Jesus the Messiah, is about God reclaiming his proper lordship over all creation. And the way God planned to rule over his creation from the start was through obedient humanity. The Bible’s witness to Jesus declares that he, the obedient Man, has done this. But the Bible is then the God-given equipment through which the followers of Jesus are themselves equipped to be obedient stewards, the royal priesthood, bringing that saving rule of God in Christ to the world.

Jesus in Luke 13.1ff.:

There were some present at that very time who told him of the Galileans whose blood Pilate had mingled with their sacrifices. And he answered them, "Do you think that these Galileans were worse sinners than all the other Galileans, because they suffered thus? I tell you, No; but unless you repent you will all likewise perish. Or those eighteen upon whom the tower in Silo'am fell and killed them, do you think that they were worse offenders than all the others who dwelt in Jerusalem? I tell you, No; but unless you repent you will all likewise perish."

The hyperbolists, of course, must insist that "perish" means something more and something less than "die violent death", and that "you" must refer to more than those then "present", and that "likewise" doesn't really mean "in the same way", and that "repent" doesn't really mean "turn your back on your former life". Jesus couldn't have possibly meant what he said literally, because then he would have been mistaken, and a mistaken Jesus is unthinkable because then he is unworshipable.

And that would be crazy!
