Whenever Mother Teresa needed help with any emergency, big or small, she prayed a “Flying Novena” based on the Memorare prayer. She prayed it nine times to ask for help, then a tenth time in thanksgiving, because she was absolutely certain that Heaven would grant her request.
Remember, O most gracious Virgin Mary, that never was it known that anyone who fled to your protection, implored your help, or sought your intercession, was left unaided. Inspired by this confidence, I fly unto you, O Virgin of virgins, my Mother. To you do I come, before you I stand, sinful and sorrowful. O Mother of the Word Incarnate, despise not my petitions, but in your mercy, hear and answer me. Amen.
