Against the flying ball no valor avails.

I've got so much work to do today, I'd better spend two hours in prayer instead of one.

This life therefore is not righteousness, but growth in righteousness, not health, but healing, not being but becoming, not rest but exercise. We are not yet what we shall be, but we are growing toward it, the process is not yet finished, but it is going on, this is not the end, but it is the road. All does not yet gleam in glory, but all is being purified.

Medicine makes people ill, mathematics make them sad and theology makes them sinful.

Next to theology I give to music the highest place and honor. And we see how David and all the saints have wrought their godly thoughts into verse, rhyme, and song.

Merit is a work for the sake of which Christ gives rewards. But no such work is to be found, for Christ gives by promise. Just as if a prince should say to me, "Come to me in my castle, and I will give you a hundred florins." I do a work, certainly, in going to the castle, but the gift is not given me as the reward of my work in going, but because the prince promised it to me.

There is on earth among all dangers no more dangerous thing than a richly endowed and adroit reason...Reason must be deluded, blinded, and destroyed.
