Touching the rock face, contemplating the grotto of more than 150 years ago and offering a prayer—these actions help visitors connect to that point in time when Bernadette hurried to this obscure cave. More importantly, they connect pilgrims to the spoken and unspoken messages that Our Lady conveyed to the young girl. As Mary bore the Son of God in her womb, she carries with her his message of love, which knows no obstacles and overcomes all shortcomings. Our lives, much like the grotto in Bernadette’s time, may be disordered, but God nonetheless comes calling. Reaching into the shadows of the caves of our own making, God seeks us through his mother.
