The provision for pain shows the presence of danger, the liability of receiving injury, and the kind design of putting men on their guard. It is the automatic guardian of our happiness. This is all that I have to say about bodily pain. "Mental suffering and pain of conscience are designed, first of all, to subserve the same purpose. The sense of guilt when a man commits a wicked act is designed, first, to lead him to repentance. It is the divine alarum placed within the soul to remind men that they have done evil and received moral damage which must be repaired. It is the moral goad which pricks men to warn them to turn from wickedness. If evil-doing were as pleasant as well-doing, men would see no difference between right and wrong; all moral ideas would be subverted and the glory and beauty of man would be trailed in the dust. "But a guilty conscience continues to trouble wicked men after the day of repentance has passed; Remorse indeed seems to rise up with preternatural power when Mercy has withdrawn for ever from the sight of Hope. What is the meaning of this? It means that which we admitted in the beginning, that sinners are guilty in God's sight, that guilt is a real thing and deserves punishment, and that God, the holy and righteous King of men, does actually punish the guilty. God is holy and abhors sin. Remorse of conscience is the shadow of the Creator's frown, the voice of his eternal indignation echoing and re-echoing in the soul of man. It is the divine wrath penetrating the human spirit and making itself felt. As the holy God abhors sin for ever, the wicked must expect to feel that abhorrence for ever. He who puts himself into a rebellious position toward his Creator must stand in that unnatural attitude guilty and suffering. We can conceive that this should be otherwise only by subverting the foundations of the moral world. Beings created in the image of God, created with a conscience and moral affections, created with moral freedom, can attain blessedness only by aspiring to heavenly things and becoming God-like. If they break away from the divine will and order, they must suffer the divine frown, they must feel that frown. How can God make his frown felt except by looking pain, so to speak, into the sinner's conscience?
