For from the error of not knowing, or understanding, what sin is, there necessarily arises another error, that people cannot know or understand what grace is.
Martin LutherSo tenaciously should we cling to the world revealed by the Gospel, that were I to see all the Angels of Heaven coming down to me to tell me something different, not only would I not be tempted to doubt a single syllable, but I would shut my eyes and stop my ears, for they would not deserve to be either seen or heard.
Martin Luther
