What do all faithful teachers have in common? What separates a good teacher from a bad one? And what do they actually do?
It’s easy to become confused about this. After all, there are plenty of speakers and teachers who are technically excellent. They are captivating personalities and incredibly gifted, yet they are a total train wreck.
Assuming the primary issue is understood—after all, the Scriptures place little emphasis on an individual’s abilities and focus almost entirely upon his conduct and character—there is really only one thing that determines if a teacher is a true one, a faithful one: how firmly he holds to Scripture. Martyn Lloyd-Jones made the point well in Life in Christ: Studies in 1 John:
The most important test is the conformity to scriptural teaching. “Hereby know ye the Spirit of God: Every spirit that confesseth that Jesus Christ is come in the flesh is of God.” How do I know that this is a scriptural test? All I know about Him, I put up to the test of Scripture. Indeed, you get exactly the same thing in the sixth verse of 1 John 4 where John says, speaking of himself and the other apostles, “We are of God: he that knoweth God heareth us; he that is not of God heareth not us. Hereby know we the spirit of truth, and the spirit of error.” The first thing to ask about a man who claims to be filled with the Spirit and to be an unusual teacher is, does his teaching conform to Scripture? Is it in conformity with the apostolic message? Does he base it all upon this Word? Is he willing to submit to it? That is the great test.
Your ability to teach matters, make no mistake. But what’s more important than your ability that you hold fast to the Scriptures. That you grab hold and never let go, no matter how tempting it may be (or how popular it may make you). Pastors, bloggers, conference speakers and authors should always be the first to say, “Do not simply take my word for it. Check the Scriptures—listen to them above me.” He doesn’t encourage closing the book, nor turning off your brain. He doesn’t imply infallibility in his ministry. He is subordinate to the Word of God. He conforms and submits to it.
That’s what a true teacher does.
