Constant at Prayer

"The disciples were constantly at prayer together, with Mary the mother of Jesus, the other women, and the brothers of Jesus." (Acts 1: 14)

One of the constant messages of Mary during her apparitions in history is to urge us to pray. Pray, pray and pray seems to me the one dominant message at Medjugorje. How best do we respond to Mary's call for prayer: the Rosary.
