It just makes it a tough sell

Why do people assume I'm trying to convince someone? I just ask myself these questions from time to time because I come from a Christian background and so to me it's like theorizing about LOST.

Here is an example where the God / Satan thing fails:

Coming back to the rain example, let's say you live in an area where water is rare. Rain is absolutely essential so your family and livestock don't starve, or so your crops don't fail.

After a long drought that could have killed you and your family, rain comes. You praise God, of course.

So there's this cycle of long, life-threatening droughts and divine intervention in the form of rain.

Who is responsible?

If God alone is responsible, he is only toying with you and your family. Pushing you to the edge of starvation so you'll have a reason to praise him.

If Satan is responsible for the drought, and God just comes in from time to time with the rain, is the situation improved in the slightest? God still makes way for Satan as soon as he is done with the miraculous intervention.

Getting us back to the original question: what is the point of praising God for the rain if he is also responsible for the drought, since it's claimed he has enough control of the situation to produce a miracle?
