Preaching and Apologetics
What’s the relationship between preaching and apologetics?
Apologetics and preaching are not two different things. Both are attempts to reach unbelievers for Christ. Preaching is apologetic because it aims at persuasion. Apologetics is preaching because it presents the gospel, aiming at conversion and sanctification. However, the two activities do have different perspectives or emphases. Apologetics emphasizes the aspect of rational persuasion, while preaching emphasizes the seeking of godly change in people’s lives. But if rational persuasion is a persuasion of the heart, then it is the same thing as godly change. God is the persuader-converter, but he works through our testimony. Other terms are also roughly synonymous (or perspectively related): witnessing, teaching, evangelizing, arguing, etc.
