Have you ever heard of Hans Scholl, the young medical student in Munich who, with his sister Sophie and a handful of others, organized the "White Rose" resistance group against the Nazis and were caught and executed in 1943? He saw the Shroud when it was being brought around Germany for public viewing when he was a teenager in the 1930's. We was deeply moved by it and it contributed to his re-conversion to Christianity, and then on to the anti-Nazi resistance.
I think God gives us sometimes these little hints, not to substitute for our faith, but to inspire it and to touch our hearts. If we are willing to be touched.
