Prayer as covenant
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.
