If he have faith, the believer cannot be restrained. He betrays himself. He breaks out. He confesses and teaches this gospel to the people at the risk of life itself.
Martin LutherThe devil is not only a liar, but also a murderer, he constantly seeks our life, and wreaks his anger whenever he can afflict our bodies with misfortune and harm. Hence it comes that he often breaks men's necks or drives them to insanity, drowns some, and incites many to commit suicide, and to many other terrible calamities. Therefore there is nothing for us to do upon earth but to pray against this arch enemy without ceasing. For unless God preserved us, we would not be safe from him even for an hour.
Martin LutherWhat would it matter if, for the sake of the Christian Church, one were to tell a big lie?
Martin LutherHe who believes in God is not careful for the morrow, but labors joyfully and with a great heart. "For He giveth His beloved, as in sleep." They must work and watch, yet never be careful or anxious, but commit all to Him, and live in serene tranquility; with a quiet heart, as one who sleeps safely and quietly.
Martin Luther
