We need to remember, first, that impatience is a manifestation of pride. We are impatient because we want to “be like God” (Gen. 3:5), who alone gets everything done all the time. God speaks, and it always happens. Nothing frustrates His will; nothing limits His accomplishments. He always accomplishes everything that He wants to accomplish, and He always does so at the precise moment that He wants it to be done. We are impatient because we are not like that, and we so desperately want to be. And since pride really is “the great sin,” as C.S. Lewis has said, we ought not to tolerate it or to turn a blind eye to it in any of its manifestations.
