No, I don’t think that Heaven and Hell are made-up ideas designed to control people. I believe that they are realities because the Bible teaches that they are real places that people will go to in the afterlife.
One of the thoughts I’ve had on this subject is that the life we live in this world leaves so much to be desired that Heaven does not seem like a story. It seems like the fulfillment of all human hopes and wishes. There will be no death in Heaven. There will be no sin or evil in Heaven. There will be no pain or suffering in Heaven.
Heaven will leave nothing to be desired. Infinite fulfillment.
And Hell fulfills the God’s justice.
Unfortunately, without salvation through faith in Jesus, we would also be among those who will receive God’s just punishment because of their sins.
