But when pragmatism is used to make judgments about right and wrong, or when it becomes a guiding philosophy of life and ministry, it inevitably clashes with Scripture. Spiritual and biblical truth is not determined by testing what "works" and what doesn't. We know from Scripture, for example, that the gospel often does not produce a positive response (1 Cor. 1:22, 23; 2:14). On the other hand, Satanic lies and deception can be quite effective (Matt. 24:23, 24; 2 Cor. 4:3, 4). Majority reaction is no test of validity (cf. Matt. 7:13, 14), and prosperity is no measure of truthfulness (cf. Job 12:6). Pragmatism as a guiding philosophy of ministry is inherently flawed. Pragmatism as a test of truth is nothing short of satanic.Nevertheless, an overpowering surge of ardent pragmatism is sweeping through evangelicalism. Traditional methodology—most notably preaching—is being discarded or downplayed in favor of newer means, such as drama, dance, comedy, variety, side-show histrionics, pop-psychology, and other entertainment forms. The new methods supposedly are more "effective"—that is, they draw a bigger crowd. And since the chief criterion for gauging the success of a church has become attendance figures, whatever pulls in the most people is accepted without further analysis as good. That is pragmatism.
