We must confide ourselves to the Heart of Mary in view of our consecration to God. We offer ourselves to this divine consecration through Mary, for she points the way to the heart of Jesus.
The main difference between the devotions to the hearts of Jesus and Mary ... to unite mankind to God through Mary's heart, and this process involves the ideas of consecration and reparation.
For wherever you enter, you obtain the grace of conversion and growth in holiness, since it is through your hands that all graces come to us from the most Sacred Heart of Jesus.
