An excerpt from “One Lord, One Spirit, One Body for All Time and All Peoples” by John Piper:
But beware of a modern mistake here. Humble does not mean wishy-washy when it comes to truth. Forbearing does not mean saying: truth doesn’t matter. It is a great mistake to confuse humility with uncertainty. But many today do confuse them. They think that the only humble demeanor is the uncertain, vague, iffy demeanor.
Is that what Paul meant? The only way to preserve the unity of the Spirit is to be vague, uncertain in your grasp of truth? He didn’t seem to be that way. I think G.K. Chesterton put his finger on our problem fifty years ago in a little book called Orthodoxy:
What we suffer from today is humility in the wrong place. Modesty has moved from the organ of ambition. Modesty has settled upon the organ of conviction; where it was never meant to be. A man was meant to be doubtful about himself, but undoubting about the truth; this has been exactly reversed. Nowadays the part of a man that a man does assert is exactly the part he ought not to assert–himself. The part he doubts is exactly the part he ought not to doubt–the Divine Reason. (G.K. Chesterton, Orthodoxy, p.55)
