Why praying without ceasing ?

The Catechism of the Catholic Church, promulgated by Pope John Paul II, recommends this prayer to Catholics.

" 2667 This simple invocation of faith developed in the tradition of prayer under many forms in East and West. The most usual formulation, transmitted by the spiritual writers of the Sinai, Syria, and Mt. Athos, is the invocation, "Lord Jesus Christ, Son of God, have mercy on us sinners." It combines the Christological hymn of Philippians 2:6-11 with the cry of the publican [Lk 18:9-14] and the blind men begging for light.[Matt. 9:27] By it the heart is opened to human wretchedness and the Savior's mercy.
2668 The invocation of the holy name of Jesus is the simplest way of praying always. When the holy name is repeated often by a humbly attentive heart, the prayer is not lost by heaping up empty phrases, but holds fast to the word and "brings forth fruit with patience." This prayer is possible "at all times" because it is not one occupation among others but the only occupation: that of loving God, which animates and transfigures every action in Christ Jesus."

"We must pray literally without ceasing - without ceasing; in every occurrence and employment of our lives. You know I mean that prayer of the heart which is independent of place or situation, or which is, rather, a habit of lifting up the heart to God, as in a constant communication with Him."
- Saint Elizabeth Ann Seton -
