And I, when I came to you, brothers, did not come proclaiming to you the testimony of God with lofty speech or wisdom. For I decided to know nothing among you except Jesus Christ and him crucified. And I was with you in weakness and in fear and much trembling, and my speech and my message were not in plausible words of wisdom, but in demonstration of the Spirit and of power, so that your faith might not rest in the wisdom of men but in the power of God.
— 1 Corinthians 2:1-5
 

Someone who successfully emphasizes doing what ‘works’ is described as being practical or pragmatic. They are simply providing a solution by implementing the most effective method in order to get the desired results. Being pragmatic is good and even necessary for much of our natural lives. However, when being pragmatic becomes the guiding philosophy for truth in our spiritual life and ministry, it sharply conflicts with Scripture. This dangerous philosophy is known as "Pragmatism." Therefore, to say doctrine matters more than results is to say that whenever biblical instruction departs from what are otherwise accepted as practical and effective methods, we must remain committed to the authority of Scripture, trusting in God’s wisdom above our own. It means our methods of identifying truth and getting results are not determined by a philosophy of man but by the Word of God.

Pragmatism says, “If it delivers result, then it is good and true. Here-in lies the danger of pragmatism. It shows a subjective commitment to results for which we are ultimately not responsible, and spiritually speaking, incapable of producing. Pragmatism causes us to take matters into our own hands in order to get the results we believe are important.
