Do you believe God targeted your father for cancer? Or do you believe God failed to save your father from cancer? Do you believe this would be the role of God if one existed?
I believe that the purpose of “God” is to put us in unpleasant situations to see how we respond.
I’ve changed my belief now, but at the time I felt “God” should have saved him. I no longer believe that’s the role “God” plays in the Universe.
I now believe “God” simply exists to judge our ability to deal with the horrible situations we are put in during the course of our lives.
