Daughter, where you cannot be, your prayer acts. You can from a distance bring about a conversion, open up a vocation, alleviate a suffering, assist someone dying, guide someone who is responsible, bring peace to a home, sanctify a priest.
You can make someone think of Me, bring out an act of love, make charity grow in a heart, repel a temptation, calm anger, smooth harsh words. What cannot be done in the invisible parts of My Mystical Body! You do not know the mysterious links which unites ones to others and of which I am the Center.
