Well, no. They believe that they could petition god through prayer to change the weather. For example to end a drought. There is a fine line between magic and prayer of this sort. If its really his will, then there seems to be little one could about it.
I think some preachers have outright commanded some weather to change, like casting a spell. "in the name of jesus’ of course. That is like a passcode, I suppose. I am sure sometimes it ‘works’ and other times it does not! Of course its a miracle, if and when the weather happens to change after such statements.
I have also read about Hindus claiming one could obtain siddhi powers after doing rituals, or chanting mantras for some particular amount of time. The number of times to obtain siddhi is often in the millions. One power is the control over weather, another is the power to do anything one desires to happen. Its a bit different from Christianity, as mantra ideally is to bring one in alignment with the divine. So, is one doing what one wishes, or is one just becoming the means for the divine manifest its will?
