As a pastor of a church plant with many new Christians, I found 7 Truths that Changed the World by Kenneth Richard Samples, to be a great foundation for a sermon series on the simple foundational truths of Christianity. The author does a great job of taking very complex subjects and making them palatable for the common reader like me. The book is not overbearing with the amount of information, nor is it too weak in defending the truth. It is a perfect balance between the academic and practical.
Since the first century, the church has been involved in one way or another in the ministry of apologetics. Within the last few decades, as atheists have seemed to ramp up their religious efforts to discredit and eradicate the belief in God and Christianity more specifically, Christians have ramped up their apologetical focus with matching intensity.
It is probably not a stretch to say that the task of Christian apologetics has been necessary since the Fall. Fallen man rejects God and in his rejection casts doubt on the validity of Christianity. If you need evidence for this then just pick up any recently published book from the “new atheists” (Richard Dawkins, Christopher Hitchens, Daniel Dennett or Sam Harris). If reading any one of these authors does not impress upon you the necessity of apologetics then not much will.
Throughout the history of apologeitcs, and more so within the last 50 years, there have been many formidable Christian apologists. These defenders of the Christian faith have serviced the church and any inquiring unsaved minds with many written apologetic works. Many of these works deal with single issues within the field of apologetics such as methodology, defending its importance or necessity, dealing with specific issues like the resurrection of Christ or the five theistic arguments from natural theology, addressing and answering Old and New testament issues and a host of other related subjects.
Douglas Groothuis is a long time Christian apologist, author and professor of philosophy at Denver Seminary and Metropolitan State College of Denver. He has recently written a new book on Christian apologetics titled Christian Apologetics: A Comprehensive Case for Biblical Faith. Groothuis does something that few if any other apologetic works have ever done. As the subtitle indicates, Groothuis has written a truly comprehensive book on apologetics, weighing in at 730 plus pages. Granted, given the vast field of apologetics, what is covered in this book is not exhaustive nor is it intended to be. However, Groothuis has provided us with a magnificent introductory work on Christian apologetics that will serve the laymen, pastor and student alike. Christian Apologetics is a go-to guide for not only the beginning student of apologetics but the more seasoned apologists among us.
