Here is a quote from Martin Luther, and then a couple of sentences after it that I liked, on page 246.
(an exhortation written in a letter to Philip Melanchthon) "Be a sinner, Philip, and sin boldly! Only still more boldly believe and rejoice in Christ!" Modern critics have cited this famous statement as proof that justification by faith leads to antinomianism. Such an interpretation, however, fails to see how accurate a description it was of Luther himself at this time -- truly the boldest sinner in Christendom.
