Hell exists because unbelievers are eternally guilty. The powerful lesson to be learned is that no human being’s suffering can ever be a payment for sin. If our suffering could erase even the most insignificant sin, then those in hell would eventually be freed after their debt was paid. But all human goodness and suffering from the beginning of time, if added together, could not cancel so much as a single sin. Could my zeal no respite know, could my tears forever flow, all for sin could not atone; Thou must save, and Thou alone. “Rock of Ages”
