"If you are a preacher of Grace, then preach a true, not a fictitious grace; if grace is true, you must bear a true and not a fictitious sin. God does not save people who are only fictitious sinners. Be a sinner and sin boldly, but believe and rejoice in Christ even more boldly. For he is victorious over sin, death, and the world...pray boldly - you too are a mighty sinner." (Weimar ed. vol. 2, p. 371; Letters I, "Luther's Works," American Ed., Vol 48. p. 281- 282)
Luther, Luther, Luther...you and the Apostle Paul were so scandalous. You were so unapologetic with the Gospel. You preached grace straight up - no fruity mixed concoctions in your preaching. Reading your words is much like throwing back a shot of 100 proof whiskey...or getting slapped in the face. We either decide we hate it, or we thank you because we need it.
