The 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 LutherWhen one is possessed with doubt, that though he call upon the Lord he cannot be heard, and that God has turned him heart from him, and is angry ... he must arm himself with God's Word, promising to hear him.
Martin LutherI've got so much work to do today, I'd better spend two hours in prayer instead of one.
Martin LutherWe are not to look upon our sins as insignificant trifles. On the other hand, we are not to regard them as so terrible that we must despair. Learn to believe that Christ was given, not for picayune and imaginary transgressions, but for mountainous sins; not for one or two, but for all; not for sins that can be discarded, but for sins that are stubbornly ingrained.
Martin LutherHe who receives a sacrament does not perform a good work; he receives a benefit. In the mass we give Christ nothing; we only receive from Him.
Martin Luther
