"I beg and admonish faithfully all devout Christians that they not be offended or stumble over the simple stories related in the Bible, nor doubt them. However poor they may appear, they are certainly the words, history, and judgments of the high divine Majesty, Power, and Wisdom. For this is the book which makes all wise and clever people fools, and can only be understood by simple people, as Christ says (Matthew 11:25). Therefore let go your own thoughts and feelings and esteem this book as the best and purest treasure, as a mine full of great wealth, which can never be exhausted or sufficiently excavated. thus you will find the divine wisdom which God presents in the Bible in a manner so simple that it damps the pride of clever people and brings it to nothing. In this book you find the swaddling clothes and the manger in which Christ lies, and to which the angel directs the shepherds. Those swaddling clothes are shabby and poor, yet precious is the treasure wrapped in them, for it is Christ."  –Martin Luther
