“God’s ear hears the heart’s voice,” said Augustine in his commentary on Psalm 148.[6] “It is the heart that prays,” said Father Jean-Nicolas Grou. “It is to the voice of the heart that God listens, and it is the heart that he answers.”[7] “We do not know what we ought to pray for,” admits the apostle Paul, “but the Spirit himself intercedes for us through wordless groans. And he who searches our hearts knows the mind of the Spirit.”[8]
