Luke's Gospel speaks about Mary's heart twice the first at the Adoration of the Shepards "But Mary kept all these words, pondering them in her heart." (Luke 2:19) and again at the Prophecy of Simeon "And Simeon blessed them, and said to Mary his mother: Behold this child is set for the fall, and for the resurrection of many in Israel, and for a sign which shall be contradicted; And thy own heart a sword shall pierce, that, out of many hearts, thoughts may be revealed.(Luke 19:34-35)
The Heart is a symbol of Love, as the Sacred Heart is a symbol of the Divine Love of Christ, Mary's Heart is the symbol of Pure untainted love for Christ. Mary carried Jesus for 9 months in her womb, held him in her arms as an infant, played with her Child, taught him the Jewish religion and raised him to adulthood. The Joy and Love of that house hold, The Joy she shared with Jesus in unity with her divine son she kept all that in her heart as all mother do!!! but we have to remember the intense suffering that Mary suffered in her heart. The fear of loosing Jesus on the pilgrimage to Jerusalem, The flight into a foreign land to avoid the slaughter of the innocence, Jesus leaving Home to start his public ministry, and finally the intense suffering of a mother watching her son suffering and being put to death!!
All this Mary kept in her heart and she United all her Joys all her suffering to the heart of her divine son Jesus. In this Mary's heart was ever overflowing with the love of the Divine!
during the apparitions of Our lady in Fatima Portugal she said to the three shepherd children "In the end my Immaculate Heart Will Triumph and there will be peace)
Many have pondered "what is this Triumph?" to me the Triumph of Mary's Heart is that when we love as she loves with that Intense Love for God, that it overflows out into the world and converts hearts to the same! Let us pray that our hearts can be like Mary's, and that we may love God and all those around us!!
