Renowned theologian John Frame sheds much-needed light on the message and method of genuinely Christian apologetics in this landmark title. He insightfully examines apologetics in terms of proof, defense, and offense and clarifies the relationships of reason, proofs, and evidences to faith, biblical authority, and the lordship of Christ. Two subjects of particular note are Frame's fresh look at probability arguments and a stimulating investigation into the problem of evil. Some of the most valuable elements of this book are Frame's extensive use of Scripture and his presentation of specific lines of argument. There is also a model dialogue in the concluding chapter that shows how these lines of argument work in conversation. This is an extensively redeveloped and expanded version of Frame's previous work, Apologetics to the Glory of God.
