The Bible warns against these folks. Jude speaks of false teachers who are identified as “grumblers, finding fault, following after their own lusts” (Ju. 1:16). We’re familiar with Moses and the “grumblers” he had to deal with (Nu. 14:36; cf. Psm. 106:25; 1 Cor. 10:10). Some of these folks are so arrogant they have no problem complaining about the Lord, or worse, complaining directly to the Lord Himself (Dt. 1:27). God had to reprove Job, “Will the faultfinder contend with the Almighty?” (Job 40:2). Despite the clear command in Philippians 2:14 to “do all things without grumbling or disputing,” these people who seem to know nothing about edification and encouragement, persist in their destructive behavior. Kent Hughes concluded, “[These] hostile, quick-to-see-the-worst, graceless [individuals] are as old as the church” (2 Corinthians, p. 38). Every church deals with them. Every leader deals with them.
