Philosopher and Theologian J.P. Moreland has recently come out with a new book entitled The God Question: An Invitation to a Life of Meaning.
For those of you familiar with the writings and lectures of Moreland, this book hardly needs endorsement. J.P. has done wonderful work over the last few decades in the areas of Christian philosophy, apologetics, and spiritual formation. This book carries on that tradition. It is particularly good to give away to non-Christian friends or skeptics who are genuinely interested in examining the truth claims of the Christian faith and discovering true meaning and purpose in life. I gave out several just this Christmas.
You can read Moreland's own summary of his book here.
