She answers it by taking our petitions to Jesus, but I do think it goes further than that. Perhaps it means that she can also, with God’s permission, answer us in many ways, through Scripture, circumstances, friends, apparitions, healings, peace, joy, feelings, etc. I think, since God gave her to us as our mother, we can expect her to answer us as a mother would.
I know myself, a couple of years ago, when I was just beginning to think that perhaps the Catholic Church was the true church, sent up my first feeble, tentative prayer to Mary. I was feeling incredibly sad and lonely that night, and I immediately felt completely enveloped in warm, radiant love. And I could tell that it was a feminine love…something entirely different than the peace I had felt from God before. I knew, without a doubt, that it was Mary. From that moment on I knew I would be coming home to the Catholic church.
I know God allows other saints to answer us. St. Therese promised to send us roses as sign of answered prayer. I was hesitant to say too much and overstep correct theology, but I think it is correct to say, that united with God, through His power, she does hear and answer us, and meets us right where we are. She is active in bringing us to her Son. And as her apparitions show, she is very involved in our lives herself. Our prayers are laying roses at her feet, and she loves our devotion.
