According to Scripture, it is the heart that prays. If our heart is far from God, the words of prayer are in vain.
“For me, prayer is a surge of the heart; it is a simple look turned toward heaven, it is a cry of recognition and of love, embracing both trial and joy.”
— St. Thérèse of Lisieux, as quoted in paragraph 2558
— Catechism of the Catholic Church, paragraphs 2562, 2558
