Since Mary was the first and perfect adorer of Jesus, the only one who truly glorified the Father through her love for Jesus, it's only natural to ask and implore our Mother to teach us to adore, to come and adore her Son with us today in the Blessed Sacrament.
In this way, we unite our love for Jesus with Mary's praise and perfect love. Jesus accepts our hour of adoration as if it were Mary herself praying. No matter how weak our faith or how poor our love, Mary places us in her Heart, and Jesus accepts our hour as if it came directly from his Mother's own Heart.
Mary's Immaculate Heart makes up for what is lacking in our own hearts. If our faith and love for Jesus are weak, if we are distracted and unaware of Jesus' real presence, then with Mary's help, we will worship with her faith, with her Heart, with her tenderness.
