This one have impressed me since young age. I've been linking it to many archetypal ritual 3 phases fights for life and death  The 3rd phase is the final blow, the one intended from the start. The first 2 are for the show and the edification of the masses. (see the rituals of a corrida)

So the strongest blow of the tempter was power over "all the kingdoms of the world and their splendor". How could the devil promise it if it was not his to give? And Jesus had no problem admiting that, his problem was with the worshiping part of the deal.

Can we conclude that all secular power over earthly kingdoms is a blessing of the tempter and not a blessing of -O-?
