When the devil throws our sins up to us and declares that we deserve death and hell, we ought to speak thus: ‘I admit that I deserve death and hell. What of it? Does this mean that I shall be sentenced to eternal damnation? By no means. For I know One who suffered and made satisfaction in my behalf. His name is Jesus Christ, the Son of God. Where he is, there I shall be also.’
Martin Luther, quoted in The Unquenchable Flame by Michael Reeves (pg. 178).
