"""This booklet offers a most concise, yet thorough-going presentation of Presuppositional Apologetics. Bahnsen's rigorous exegesis, logical consistency and cogent style provide a superbly persuasive primer on defending the Christian faith in a Biblical manner. This resource will prove particularly valuable for those involved in ministry to an unbelieving culture."" - Brian De Jong, Grace OPC (Sheboygan, Wisconsin) ""Never was it more important for the Christian church to retain a right biblical apologetic than at the present. The raging age of skepticism and Christian apostasy calls for a rock-solid, biblically-based, presuppositional apologetic as so elegantly, simply, and succinctly laid out here by Dr. Greg Bahnsen. I recommend this for every Christian leader and lay person."" - Kevin Swanson, Pastor, and Director of Generations.org"
