SHEDD ON DREADFUL CLARITY OF ETERNAL PUNISHMENT

The fall and eternal ruin of an immortal spirit is the most dreadful event conceivable. That some of God’s rational and self determined creatures will forever be in dead enmity to him, cannot bethought of without sorrow and awe. But from the nature of finite free will, it is a possibility; and it is reviewed to us as a fact, as clearly as the facts of the incarnation and redemption.”
