As Kingfishers Catch Fire: A Conversation On the Ways of God Formed By the Words of God by Eugene H. Peterson is a collection of sermons preached by Peterson over the twenty-nine years he was pastor of Christ Our King Presbyterian Church in Bel Air, Maryland. The sermons are grouped into seven sections of seven sermons, with each group headed by a different figure from the Bible who plays prominently in the section of scripture each sermon is taken from.
Peterson's writings are always filled with rich insights about scripture. The most notable insights in this book are the parallels between the old and new testaments that he points out. In multiple sermons in each section, he draws a parallel that, to me at least, was previously unclear, and once pointed out, adds a new level of richness to those particular scriptures.
Each sermon takes up about six or seven pages. There isn't really a flow to this book since each sermon is self-contained. That can make reading it somewhat frustrating to read unless one approaches it with the right mindset. However, the insights gained and the depths of scripture opened up far outweigh any frustrations. I'd recommend As Kingfishers Catch Fire to anyone interested in the Bible.
