An aging leader of a mega church in present-day Nashville loses his faith and convinces his followers that God wants him preserved by cryogenics when he dies - for a mission to the future. He gets his wish and 140 years after dying is reanimated.
One has to be careful, of course, what one wishes for: His church has become a major faith, and millions of faithful view him as a prophet. Further, the US has fragmented into spheres of influence controlled by various faiths. And, oh yes, the leaders of his church view him as a threat, had no desire to reanimate him - it was done illicitly - and wish to return him to 'suspended animation.'
Into the ensuing sci-fi adventure story, the novel weaves reflections on faith and its corruption, along with satire on efforts to erode church/state separation.
