The Psalms have been for faithful Christians the source of song and praise and, along with the Lord’s Prayer, the pattern for our most earnest and joyful prayers.
For then we confuse wishes, hopes, sighs, laments, rejoicings—all of which the heart can do by itself—with prayer. And we confuse earth and heaven, man and God. Prayer does not mean simply to pour out one’s heart. It means rather to find the way to God and speak with him, whether the heart is full or empty” (Dietrich Bonhoeffer, Psalms: The Prayer Book of the Bible [Minneapolis: Augsburg Fortress, 1974], 9).
