Pray for Your Sister

"You tell me that you pray very often for your sister. Since you have goodness to do this, I would be very happy if you will agree to say this prayer for her every day. It sums up all her desires.: 'Merciful Father, in the name of our lovable Jesus, of the Virgin Mary and of the Saints, I ask you to set my sister on fire with Your Spirit of Love, and to grant her the grace of making You deeply loved.' " 

(From a letter written by St. Therese of Lisieux to Maurice Belliere, 2/24/1897)
