How is God's name hallowed among us? When both our doctrine and living are truly Christian.

Where faith is not continually kept in motion and exercised, it weakens and decreases, so that it must indeed vanish; and yet we do not see nor feel this weakness ourselves, except in times of need and temptation, when unbelief rages too strongly; and yet for that very reason faith must have temptations in which it may battle and grow.

The Devil, it is true, is not exactly a doctor who has taken degrees, but he is very learned, very expert for all that. He has not been carrying on his business during thousands of years for nothing.

Faith, like light, should always be simple and unbending; while love, like warmth, should beam forth on every side, and bend to every necessity of our brethren.

One thing, and only one thing, is necessary for Christian life, righteousness, and freedom. That one thing is the most holy Word of God, the gospel of Christ.

It is cheering to note that [Martin] Luther (1524) did not see why schools should not be fun as well: "Now since the young must leap and jump, or have something to do, because they have a natural desire for it which should not be restrained (for it is not well to check them in everything) why should we not provide for them such schools, and lay before them such studies?

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.
