Catechism of the Catholic Church
2616 Prayer to Jesus is answered by him already during his ministry, through signs that anticipate the power of his death and Resurrection: Jesus hears the prayer of faith, expressed in words (the leper, Jairus, the Canaanite woman, the good thief) 84 or in silence (the bearers of the paralytic, the woman with a hemorrhage who touches his clothes, the tears and ointment of the sinful woman). 85 The urgent request of the blind men, "Have mercy on us, Son of David" or "Jesus, Son of David, have mercy on me!" has-been renewed in the traditional prayer to Jesus known as the Jesus Prayer: "Lord Jesus Christ, Son of God, have mercy on me, a sinner!" 86 Healing infirmities or forgiving sins, Jesus always responds to a prayer offered in faith: "Your faith has made you well; go in peace."
St. Augustine wonderfully summarizes the three dimensions of Jesus' prayer: "He prays for us as our priest, prays in us as our Head, and is prayed to by us as our God. Therefore let us acknowledge our voice in him and his in us." 87
