Everything that is done in the world is done by hope. No merchant or tradesman would set himself to work if he did not hope to reap benefit thereby.
Our preaching does not stop with the law. That would lead to wounding without binding up, striking down and not healing, killing and not making alive, driving down to hell and not bringing back up, humbling and not exalting. Therefore, we must also preach grace and the promise of forgiveness--this is the means by which faith is awakened and properly taught. Without this word of grace, the law, contrition, penitence, and everything else are done and taught in vain.
The devil, the originator of sorrowful anxieties and restless troubles, flees before the sound of music almost as much as before the Word of God....Music is a gift and grace of God, not an invention of men. Thus it drives out the devil and makes people cheerful. Then one forgets all wrath, impurity, and other devices.
I do not deny that medicine is a gift of God, nor do I refuse to acknowledge science in the skill of many physicians; but, take the best of them, how far are they from perfection? A sound regimen produces excellent effects. When I feel indisposed, by observing a strict diet and going to bed early, I generally manage to get round again, that is, if I can keep my mind tolerably at rest. I have no objection to the doctors acting upon certain theories, but, at the same time, they must not expect us to be the slaves of their fancies.
