Martin Luther - Old Testament

I beg every devout Christian not to despise the simplicity of language and the stories found in the Old Testament. He should remember that, however, simple the Old Testament may seem, it contains the words, works, judgments and actions of God himself. Indeed the simplicity makes fools of the wise and the clever, and allows the poor and simple to see the ways of God. Therefore submit your thoughts and feelings to the stories you read, and let yourself be carried like a child to God.
Martin Luther
