A very short, but good introduction to some themes in the Psalms. As usual, Bonhoeffer connects the Psalms to Jesus and shows how we can only pray them by looking at Christ. A lot of wonderful insight into how the Psalms affect our prayer life. He closes with a short exhortation to morning prayer. This book would be good to pick up every now and then to put some spiritual adrenaline back in one’s prayer life.
