I have previously suggested Peter Kreeft's annotated edition of Pascal's Pensees (Christianity for Modern Pagans) as the best book for modern, intellectual Christian seekers - but now I am inclined to change that recommenation to Handbook of Christian Apologetics: hundreds of answers to crucial questions by Peter Kreeft & Ronald Tacelli.
Whatever the choice, it is clear to me that Peter Kreeft is a treasure - Christians have been very lucky to have him.
Kreeft is by so great a margin the best (wisest, clearest, most enjoyable) of living Christian apologists and explainers (of whom I am aware) that it is very hard to identify the second best.
Given the state of things, we really don't deserve anybody this good - still, there he is.
Be thankful we do not get what we deserve.
