This is perfected by other acts of piety, especially by devotion to the Sacred Heart of Jesus. The daily life of each member is thus converted into a sacrifice of praise, reparation, and impetration. In this way the forces implanted in Baptism are activated and the Christian offers his life as a sacrifice in and with Christ for the honor of God the Father and for the salvation of souls. All the sacred practices of which the Apostleship of Prayer makes use to round out and to perfect this oblation, taken together, contain the sum total of Christian perfection. Through this sacrifice demanded by the apostolate, they put into the hands of all men the means by which Christians sanctify their lives.
Personal holiness renders their apostolate most fruitful.
If the reverend pastors will introduce the flocks committed to their care to the spiritual practices of the Apostleship of Prayer, they will satisfy no small part of their pastoral obligations. For when they persuade the faithful to make the daily Morning Offering, they are teaching them that one's whole life should be offered, together with the offering of Christ, to God the Father. They are teaching them that they should aspire daily to the perfection of Christian life, in which each one tries to make himself a worthy offering to God. When they prompt the faithful to unite this self-offering with the Eucharistic Sacrifice and to approach the Holy Table as often as possible in a spirit of reparation, these reverend pastors are teaching their people to consider the unbloody Sacrifice of the Altar as the very center of their lives. Moreover, when a pastor urges his people, as devoted children of Mary, to make their daily offering through her, when he persuades them to say the Rosary in honor of her merciful and loving heart, he is instilling in them an active and solid devotion to the Virgin Mother of God.
