"Who Needs Theology?" is an excellent introduction to an important and often misunderstood aspect of the Christian faith. Touching on Jesus' command to "Love the Lord your God with... all your mind..." Grenz and Olson demonstrate that the discipline of theology is designed to do just that.
The book is written at a high school/ undergraduate level and can be easily understood with a minimum of new vocabulary.
The only drawback to the work is that the authors begin nearly every chapter by recounting a "Peanuts" comic strip- I wish the publishing house had acquired the rights to reprint the strips.
If you are starting your theology endeavor this is a great book for you. Grenz and Olson start from the scratch opening our eyes to the truth that everyone is a theologian, the matter is what kind of theologian are we and what kind of theology do we make? They also explore the theologys task, tradition and tools to build a contextualized bridge to our context.
This text links concentric circles of Biblical premise, historical-heritage element, and cultural consideration to help the reader form a practical view of study that presents the Christian message. Clearly written with well-chosen examples, this text is approachable to the seeker and reminds the more advanced Theological student of the study's intended simplicity.
