I think to say "it is likely that he would have reasons for acting that are beyond our ability to understand" destroys the meaning of thinking about his existence and god in general in the first place. As a general statement I would say there is no god but he exists in way. He is the order and the meaning in our universe with no order and no meaning. A religion isnt ment to be proven but the only condition is to believe. I could share tons of personal experiences why believing in god is a good think and i m very sad that I cant but I will also point out to Nietzsche s theory which includes the idea that without religion people fall into extreme ideologies(we can observe it in the current political climate)

In conclusion its impossible to prove gods existence and we should not try it. Besides the harm religion can cause, in the long run it saves many people, we can not judge god and we should not because then we might discover there is no all loving god controlling the universe and we will be forced living in a cruel meaningless universe with no good, no bad.
