"And his mother kept all these things in her heart." (Luke 2:51)
It's a beautiful little line that St. Luke gives us, and it reminds us that Mary kept in her heart all the mysteries of the earthly life of Jesus Christ. And not just the mysteries about which we know something, like his birth in Bethlehem and his passion and death on the Cross, but also those aspects of Jesus' life that we cannot know, like what he was like as a boy, how it was to observe him working with St. Joseph, and all the other blessed details of a daily life lived with the Son of God.
When we think about this, we realize that Mary knows Jesus better than any other person who ever lived, or will ever live. This realization forms part of our motivation for turning to Mary in our desire to follow after Jesus. It is she who knows best him whom our hearts desire and whom we wish to follow.
Let us turn, then, to the Immaculate Heart of Mary, that place of safe-keeping and cherishing of all the mysteries of the Word of God made man in Jesus Christ. May she obtain for us the grace of knowing Jesus ever more fully and deeply, and may we too keep, protect, and cherish his presence in our own hearts.
