The Bible records many prayers, but in this passage we have the only account of a prayer from Hell!
"And he cried and said, Father Abraham, have mercy on me, and send Lazarus, that he may dip the tip of his finger in water, and cool my tongue; for I am tormented in this flame" (Luke 16:24).
...The doctrine of hell is one of the most neglected doctrines in all of Scripture. When hell is mentioned today, it is generally ridiculed, as if the whole idea of hell were so old-fashioned that only the naive and ignorant would really believe that such a place actually exists. This is not hard to understand. Natural men hate the idea of being held accountable for their lives to a holy God...
Matthew 13:49,50: So shall it be at the end of the world: the angels shall come forth, and sever the wicked from among the just, and shall cast them into the furnace of fire: there shall be wailing and gnashing of teeth.
"Ye generation of vipers, how can ye escape the damnation of hell?" (the words of Jesus Christ in Matthew 23:33)
