There is on earth among all dangers, no more dangerous thing than a richly endowed and adroid reason, especially if she enters into spiritual matters which concern the soul and God. For it is more possible to teach an ass to read than to blind such a reason and lead it right; for reason must be deluded, blinded, and destroyed.
Martin LutherIf the gospel was of a nature to be propagated or maintained by the power of the world, God would not have intrusted it to fishermen. To defend the gospel appertains not to the princes and pontiffs of this world.
Martin LutherAs concerning faith we ought to be invincible, and more hard, if it might be, than the adamant stone; but as touching charity, we ought to be soft, and more flexible than the reed or leaf that is shaken with the wind, and ready to yield to everything.
Martin LutherIt is not necessary for a preacher to express all his thoughts in one sermon. A preacher should have three principles: first, to make a good beginning, and not spend time with many words before coming to the point; secondly, to say that which belongs to the subject in chief, and avoid strange and foreign thoughts; thirdly, to stop at the proper time.
