"Mary by a singular privilege granted to no other saint, loved, and was always actually loving God, in every moment of her life, with such ardor, that St. Bernard declares, it required a continued miracle to preserve her life in the midst of such flames." -St. Alphonsus di Liguori, The Glories of Mary, (Tan Books: 1978), 411.
In other words, the Blessed Mother was in a constant state of serving and loving God. Likewise, God was in a constant state of loving Mary. So it took a constant miracle for Mary to not simply be consumed by the fire of God's love!
In preparation in anticipation for the coming of Christ. Let's not waste the time being consumed by material matters.
