Question: Does G-d personally control all storms of water or does he allow his angels to direct and control these things?
Answer: One might view the laws of nature that God put into existence as “angels” or His “agents”, but they are not just that. In fact, there are two types of rain. Rain which comes about because of the laws of nature God instituted from the beginning and rain that comes only by prayer or His direct providence.
So, whether by His laws or by His providence He is in control.
All the Best,
Rabbi Azriel Schreiber
