Hereby we may understand that God, of His special grace, maketh the teachers of the gospel subject to the Cross, and to all kinds of afflicitons, for the salvation of themselves and of the people; for otherwise they could by no means beat down this beast which is called vain-glory.
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 LutherIf then, Moses so distinctly announces that there is in us not only a faculty, but also a facility for keeping all commandments, why are we sweating so much? ... What need is there now of Christ or of Spirit? We have found a passage that asserts freedom of choice, but also distinctly teaches that the keeping of the commandments is easy.
Martin LutherGod creates out of nothing. Therefore, until a man is nothing, God can make nothing out of him.
Martin Luther
