Well, I watch Joyce Meyer and 700 club and they are big on prayer.  They say you have to do it and God answers them.  It still does not explain why some are not answered.  But, your explanation doesn't make sense, either, because it is said he knows everything and can do anything, etc....  He would have to be some sick pervert to kick back and say, "I wish you the best.", knowing of all the horrible things that happen to many people.  Everytime I want to throw in the towel, that there is no God, not one who exists now and loves us, I still cannot answer the question..where did we come from?  It is possible we came from molecules and atoms and junk, but it is hard to grasp that because our concept of being is dependent on a beginning..and that doesn't suggest how all the molecules and atoms came about in the first place.  I sometimes think it is easier just to believe in God so that those kind of questions don't need answered.  But, when one sees all the pollution and destruction and sickness, ect... in the world, it makes it very hard to swallow.  Carlin is pretty funny on the subject:
