2613 Three principal parables on prayer are transmitted to us by St. Luke:
- The first, "the importunate friend," invites us to urgent prayer: "Knock, and it will be opened to you." To the one who prays like this, the heavenly Father will "give whatever he needs," and above all the Holy Spirit who contains all gifts.
- The second, "the importunate widow," is centered on one of the qualities of prayer: it is necessary to pray always without ceasing and with the patience of faith. "And yet, when the Son of Man comes, will he find faith on earth?"
- The third parable, "the Pharisee and the tax collector," concerns the humility of the heart that prays. "God, be merciful to me a sinner!" The Church continues to make this prayer its own: Kyrie eleison!
