Mary has helped many Christians by her powerful intercession during times of military attack or military danger and by her strength of the faith of Christians. In our personal lives, what the rosary has done in a big way can be done in a small way. The rosary, we must remember, is a prayer, and it can do a great deal if we pray it. But it will do very little if you just say it. You have to give God the best time, the best place, the best posture.
