Where does prayer come from?

 Whether prayer is expressed in words of gestures, it is the whole man who prays, But in naming the sourece of prayer, Scriptures 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 our prayers are in vain. As God gradually reveals himself and reveals man to himself, prayers appears as a reciprocal call, a covenant drama. Through words and actions, this "drama" engages the heart. [ See CCC 2562, 2567 ]
