It just doesn't cut the mustard. I quote "Well - apparently God had a bit of a PR problem"... "Jesus could have performed a miracle and made the figs appear, but he preferred sour grapes instead". There's a lot more where that came from.
It's an exercise in self-indulgent writing with poor, cliched attempts at humour that does very little to advance, illuminate or inform. It's a shame because Jackson has obviously done some good thinking and research, and does have a good - and sometimes even original - take on things. However the flow of thinking is constantly interrupted and marred by banal, teenage observations which is incredibly annoying.
"Clearly Jesus was mad. Perhaps he had low blood sugar".
Perhaps indeed, but then - perhaps not...
