I really enjoy reading Douglas Wilson. I agree whole-heartedly with him 80% of the time. Unfortunately that other 20% of disagreement is on the doctrine of justification, a notion that is bound up with the very heart of the gospel as evangelicals have formulated it since the time of the Reformation. This book is great though.
It is a fictional account between Evangelist and several objectors to the Christian faith. Evangelist is on his way to the City and along the way tries to warn and persuade people who are heading to the Abyss. Wilson is a great writer, very witty, sharp, and satirical at times. Wilson is also a Van Tilian presuppositionalist. This book is all example with no theory. It is a very refreshing and easy read. Here is the table of contents:
Rev. Howe--Empty Scholarship
Jim and Sarah--Marriage
Dorothy--Hypocrisy in the Church
Bill--Salvation and Sanctification
