"Those who belive that presuppositionalism eliminates communication between believer and unbeliever underestimate God's power to reach the unbelieving heart. They also underestimate the variety and richness of a biblical apologetic, the creativity that God has given to us as his spokesmen, and the many forms that biblical apologetic can take. Here John M. Frame unveils some of the "variety and richness of a biblical apologetic." Defining apologetics as "the discipline that teaches Christians how to give a reason for their hope," he distinguishes three main kinds of apologetic: Proof -- presenting a rational basis for faith. Defense -- answering objections of unbelief. Offense -- exposing the foolishness of unbelieving thought. Frame clarifies the relationships of reason, proofs, and evidences to faith, biblical authority, and the lordship of Christ. He offers a fresh look at probability arguments and gives special attention to the problem of evil. Particularly helpful are his extensive use of Scripture and his presentation of specific lines of argument. A model dialogue in the concluding chapter shows how the various lines of argument work in a conversation with a nonbeliever. - Back cover.
