Without disguise and with perfect freedom the Psalmists prayed prayers that we might find alarming. Most disturbing are the prayers of vengeance, or what scholars call "imprecatory" Psalms. An imprecation is a curse of God's wrath called down on an enemy.
We are tempted to ask why these are in the Bible? How do they fit with Jesus' call to love your enemies? These prayers will once again remind us that God stands outside of our little box and all of Scripture is powerful and relevant.
