Sanders, Fred. The Deep Things of God: How the Trinity Changes Everything. Crossway, 2010.
This book has two notable strengths. First, it is an excellent introduction to the Trinity and its implications for the Christian life. If anyone thinks that the Trinity is an arcane doctrine that cannot have the central importance for the Christian life that Christians have historically given to, this would be a book to read. Personally. I especially appreciated the chapters on the Trinity and Scripture and the Trinity and prayer. Second, Sanders demonstrates that evangelicalism has strong Trinitarian foundations, even if sometimes only implicitly. Evangelicals have a tendency toward self-critique that can sometimes become problematic, so it was nice to read an author who, though not uncritical toward the evangelical tradition, was determined to draw on its strengths.
