Prayer

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.

Prayer is often misunderstood.  Scripture says in Romans 8:26, "we do not know how to pray as we ought."  Below are three paragraphs from the Catechism that I think will help begin one to understand prayer.  For excellent teaching on prayer read Part Four - Christian Prayer from the Catechism. (after reading that page you'll need to hit next to continue reading)

2559"Prayer is the raising of one's mind and heart to God or the requesting of good things from God." But when we pray, do we speak from the height of our pride and will, or "out of the depths" of a humble and contrite heart? He who humbles himself will be exalted; humility is the foundation of prayer, Only when we humbly acknowledge that "we do not know how to pray as we ought," are we ready to receive freely the gift of prayer. "Man is a beggar before God." (CCC)
2562
Where does prayer come from? Whether prayer is expressed in words or gestures, it is the whole man who prays. But in naming the source of prayer, Scripture speaks sometimes of the soul or the spirit, but most often of the heart (more than a thousand times). According to Scripture, it is the heart that prays. If our heart is far from God, the words of prayer are in vain. (CCC)

Prayer cannot be reduced to the spontaneous outpouring of interior impulse: in order to pray, one must have the will to pray. Nor is it enough to know what the Scriptures reveal about prayer: one must also learn how to pray. Through a living transmission (Sacred Tradition) within "the believing and praying Church," the Holy Spirit teaches the children of God how to pray. (CCC)
