I find that asking God for natural processes to continue to function results in pretty high rates of success. But God does not seem to answer many prayers for the laws of the universe to be suspended, strangely enough. From what I know of God, I’d guess that the boy’s prayer was answered in that regard, but I suspect that if he’d prayed, for whatever reason, for the food not to be digested after they ate it, God wouldn’t answer that one.
