"Note the Psalmist's words: 'I sought the Lord, and he answered me.' Where did the Lord hear? Within. Where does he reply? Within. There you pray, there you are heard, and there you are made happy.
"Therefore, enter your heart. Happy are those who delight to enter their hearts and find no evil."
-- Commentary on Psalm 33 (2), 8
Prayer. Lord, you strengthened me because I took refuge in you; and I took refuge because you freed me.
-- Commentary on Psalm 17, 3
