Luther and Participation

“After your heart has thus become firm in Christ, and love, not fear of pain, has made you a foe of sin, then Christ’s passion must from that day on become a pattern for your entire life. Henceforth you will have to see his passion differently. Until now we regarded it as a sacrament which is active in us while we are passive, but now we find that we too must be active…. That is a proper contemplation of Christ’s passion, and such are its fruits” (Luther, Devotional Writings I, LW vol. 42)
