It does NOT furnish any example of unending torment. Many think that by presenting the hideous teaching of endless torture they will cause people to flee in terror to God. Such has not happened. Those who confess Christ only because they are in fear of endless punishing are seeking fire insurance, not a fellowship with our Heavenly Father. The world is full of people who are afraid of hell, but have no interest in a daily personal walk with God.
Fear is the tool of cult leaders.
Yahweh, Holy and Righteous God, is portrayed throughout scripture as being just and merciful. His purity and righteousness are demonstrated by Jesus, His Son. Unending punishment requires a god who will submit the unredeemed to unbearable ghastly suffering, and make it impossible for them to die or ever be relieved of their torment. Such a doctrine shames and dishonors God, while giving support to pagan dogma. Endless punishment requires that those who suffer it must possess immortality, but according to the bible immortality is to be conferred ONLY upon the redeemed in the day of resurrection.
