I dont there has ever been a living person who has not suffered in this world, be it physical or mental. It might look like people live really nice lifes, but inward they suffer because there spiritually dead.
Even Jesus said let the dead bury there dead.
Jesus come for a short time to bring light into the world.
Jesus even said himself he speaks figuratively, even as he said it better to enter life with one arm than with two and go into the eternal fire. As he was explaining he was the truth but people would rather live in darkness, the fire, where there is weeping and gnashing of teeth.
The light gave truth, joy, and hope to those who would accept it and believe.
There is no literal eternal fire. Its symbolic and figurative speech. Jesus said a few times to his diciples he was speaking figuratively. He spoke figuratively, symbolics, parables, and literally.
