What do you question in your religion?

I’m sure people have at least one or two small doubts about their religion. What do you doubt? What kinds of questions have you struggled with?

Again, this is not to bash people or open up avenues to argue with you. I don’t want any argument with people. I want to understand how people see their religions. I’ve asked what they do for you, and now I want to know if you struggle with it at all, and if so, what struggles do you have.
