We all feel a special love for our own mother. But our mothers are not perfect. I believe that God has made us so that we yearn for a perfect mother to love. And that mother is Mary, the Mother of Christ our Lord. She has revealed to us that her favorite prayer is the one she instructed St. Catherine Labouré to inscribe on the front of the Miraculous Medal. It reads: "O Mary, conceived without sin, pray for us who have recourse to thee." The Holy Mother promised to obtain many graces for those who wear the medal and request them. You can search for "Miraculous Medal" online and read all about it. How Mary appeared to St. Catherine to ask her to get the medal struck is a beautiful story in itself.
