A parable meant to illustrate the folly of depending on riches. It wasn't a literal statement on the nature of hell. If it were, then you would have to believe every part of it literally. For example, you would have to believe that "heaven" means that we gaze upon our loved ones burning in hell eternally.
I can give you scripture upon scripture that shows that men perish. The myth that we ALREADY have eternal life is the oldest lie of Satan:
Gen 3:3 But of the fruit of the tree which is in the midst of the garden, God hath said, Ye shall not eat of it, neither shall ye touch it, lest ye die.
God told Adam and Eve that if they ate, they would die.
Gen 3:4 And the serpent said unto the woman, Ye shall not surely die:
Satan said, no, God's a liar. You won't die.
But they DID die and the process began at the moment they sinned.
Man is NOT immortal. That is Satan's lie.
Your assertion implies that a parable can tell a falsehood to convey the truth. Illogical, and also contrary to the principle of the inerrancy of the word. The Bible contains no fanciful theater; it uses one truth to convey another.
