I know the suffering and pain which sickness entails. I admit the misery and wretchedness which it often brings in its train. But I cannot regard it as an unmixed evil. I see in it a wise permission of God. I see in it a useful provision to check the ravages of sin and the devil among men’s souls. If man had never sinned I should have been at a loss to discern the benefit of sickness. But since sin is in the world, I can see that sickness is a good. It is a blessing quite as much as a curse. It is a rough schoolmaster, I grant. But it is a real friend to man’s soul.
