Why not? He lets good people suffer and die. Eight children were killed in the 9/11 attacks, and I find it difficult to believe that the 3,000 or so who were killed deserved death. A Christian nurse with whom I had a discussion a few weeks ago pointed out that the cancer wards are full of children. No, good people do die, so why not allow a few to wander trapped between this existence and the next? Perhaps it's an alternative to Hell? Now, I don't believe that Hell exists, but I think you do. Or perhaps they are not trapped as the secularist ghost believers think. Perhaps they are on a mission from God. Unless you have all the answers then how can you be certain?
