Listen to most Christian prayer requests and they are all about physical things–health and money primarily. The Prosperity Gospel has picked up on this theme and invented a theology to go along with it.
Apparently, great faith is rewarded by lots of physical benefits. This is amazing seeing as how God thinks much higher about eternal, unseen rewards than the temporal, seen rewards. Jonathan Edwards says it better than I:
“God never would distribute earthly enjoyments so plentifully among the wicked, while he commonly gives his own children but little, were it not that they were in themselves very worthless, a very man, worthless portion. What man in his wits would be willing to take up with that portion that God frequently allots to those that he hates most?
“If God did not see all those earthly things to be very worthless indeed, surely he would not be willing to give the very best of them to those that he hates; he would reserve some of the choicest for his favourites. But it is not so.
“He commonly gives the choicest of earthly things, the very cream of all that earth can afford, to those that he hates, yea to those that he hates with a peculiar hatred. He gives his children something of those things, so much as is necessary to carry them through their journey towards heaven.”
