Ekr gives a good analysis of the latest news on intercessory prayer. "Deciding who should be healed based on how hard they pray rather than, say, how virtuous they are or how hard they believe seems awfully... transactional."
There are few popular religions today where the written scripture says "God will do the thing you want, but only if you pray for the specific thing you want in this particular way". There is plenty of spoken support for that view, but rarely anything written, probably because writing it down makes it clear how odd it sounds when put next to the rest of the written canon.
