“If consciousness of a great sin weights you down, comfort yourself with this blood of love….No human religion can hold its own in the face of the judgment, but it is solely in the blood of Christ that we have confidence on the Day of Judgment.”
(Luther, quoted in 1-3 John: Baker Exegetical Commentary on the New Testament, Robert W. Yarbrough, Grand Rapids: Baker Academic, 2008, page 260)
