Book excerpt: Our Lady of Fatima, before appearing to the Shepherd Children, Lucia, Francisco and Jacinta, sent an angel to prepare them for their great mission. His was a simple, timely reiteration of the perennial and urgent message of Scripture: live in God's presence, whose solicitous love surrounds you, Whose plans of mercy involve your life; learn to pray much; learn to grow in love through sacrifice; help Jesus and Mary to save souls. Peace in the world depends upon these A,B,C's of Christianity; the alternative, prophetically warned and proven by history, has been wars, suffering and persecutions. This little book retells the Angel's lessons to the three shepherd children, and how they, following his guidance, grew in a short time to heroic sanctity. Thus, well prepared for the Blessed Virgin's coming at Fatima, they convincingly convey her message to those who have ears to hear. You, too, can enter this angelic school, gain new depth in your spiritual life, and so find peace, joy and purpose by conforming your life to God's salvific plan.
