I did not say that suffering drives me away from God. I said that it causes some to flee from God and abandon their faith. I knew a woman when I first began my career in government decades ago. She was the wife of a Protestant minister. They had a child of maybe 8-10 years old who had died. This resulted in a divorce and her losing her faith in God.
Why does God allow suffering? I think the best answer is pretty much what a retired cop, turned Catholic priest, said on network television a few years ago. "Life is a test. It is a test to determine where we will go in the next life". Suffering it would seem is part of this test and perhaps how we react to it is part of what determines our fate.
