Perfect model of this apostolic spiritual life is the Blessed Virgin Mary, Queen of Apostles. While on earth, her life was like that of any other, filled with labours, and the cares of the home; always, however, she remained intimately united to her Son and cooperated in an entirely unique way in the Saviour's work...Everyone should have a genuine devotion to her and entrust his life to her Motherly care." -- from the Vatican II Decree on the Apostolate of Lay People. (Underlining is mine)
When I read the above quote I was so blessed by it. How truly we need to obey Jesus' words: "Behold your Mother" and take Mary into our lives! She will surely guide us to her Son, and through Him, by the power of the Holy Spirit to Our Father.
