2. A Life of Sanctification.
The Temple is also the House of Sanctification. God led Mary there in order to prepare Her for Her high destiny: that of being the Mother of God. Later on, Jesus, before His public life, withdrew into the desert, left His house and went far away from the world in order the more intimately to contact God.
You can imagine the life of interior and external recollection which Our Lady led in the Temple. It is an image of the interior life of the soul. How fond we are of an external life! We like it and we believe that the more external works we perform, the more we move about, the more we do for God's glory. Yet a life of apostolate which is not grounded on the interior life is completely useless. God does not bless it. It yields no fruit. It is good to work for others but first, it is necessary that we work for ourselves. Ask Our Lady for a greater love of retirement, of solitude, of self-denial; pray for an increase of interior life.
