In Matthew 16:26, Jesus asked his disciples, "What profit would there be for one to gain the whole world and forfeit his life?" St. Faustina was led by an Angel to the chasms of hell. She saw these kinds of tortures: (1) loss of God, (2) perpetual remorse of conscience, (3) constancy's of one's condition, (4) terrible suffering caused by a spiritual fire penetrating the soul without destroying it, (5) continual darkness and a terrible suffocating smell, (6) the constant company of Satan, (7) horrible despair and hatred of God. There are other more special tortures too. (For a complete description, read her Diary, 741.) To me, the worst part is suffering not for a finite period of time, but for all eternity! Those who believe in God need not worry about hell, for they will end up in his company; but those who don' believe that hell exists had better be concerned about God, for they could easily end up in hell.
