If there is an all-powerful and loving God in this world, why is there so much excruciating pain and unspeakable suffering? The problem of suffering has haunted me for a very long time. It was what made me begin to think about religion when I was young, and it was what led me to question my faith when I was older. Ultimately, it was the reason I lost my faith.
