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 LutherI was born to fight devils and factions. It is my business to remove obstacles, to cut down thorns, to fill up quagmires and to open and make straight paths. If I must have some failing let me rather speak the truth with too great sincerity than once to act the hypocrite and conceal the truth.
Martin LutherI simply taught, preached, wrote God's Word: otherwise I did nothing. The Word of God did it all.
Martin LutherWhere faith is not continually kept in motion and exercised, it weakens and decreases, so that it must indeed vanish; and yet we do not see nor feel this weakness ourselves, except in times of need and temptation, when unbelief rages too strongly; and yet for that very reason faith must have temptations in which it may battle and grow.
