“There is in the Holy Scriptures one book that differs from all other books of the Bible in that it contains only prayers. That book is the Psalms. At first it is something very astonishing that there is a prayerbook in the Bible. The Holy Scriptures are, to be sure, God’s Word to us. But prayers are human words. How then do they come to be in the Bible? Let us make no mistake: the Bible is God’s Word, even in the Psalms. Then are prayers to God really God’s own Word? That seems difficult to understand. We grasp it only when we consider that we can learn true prayer only from Jesus Christ, and that it is, therefore, the word of the Son of God, who lives with us human beings, to God the Father who lives in eternity. Jesus Christ has brought before God every need, every joy, every thanksgiving, and every hope of humankind. In Jesus’ mouth the human word becomes God’s Word. When we pray along with the prayer of Christ, God’s Word becomes again a human word. Thus all prayers of the Bible are such prayers in which Christ includes us, and through which Christ brings us before the face of God. Otherwise there are no true prayers, for only in and with Jesus Christ can we truly pray.”
~ Dietrich Bonhoeffer, Psalms: The Prayerbook of the Bible (DBW5), 156-57.
