“It’s ultimately no surprise that great teachers produce other great teachers. That seems to be the way God has designed us. In Scripture, we are called again and again to be disciples, or more precisely, learners. We need teachers if we are to learn, and great teachers raise up great learners who can then go on to produce other great learners. Christ is our preeminent example of this. Because He was a great teacher, He knew what to do in order to take a ragtag bunch of fishermen, Zealots, and tax collectors, and make them into the most influential bunch of learners the world has ever known. From their ranks we have been blessed with great teachers—Matthew, John, Peter, and others whose work continues to impact the world to this day. Of course, these men were inspired by the Holy Spirit in a manner that other teachers aren’t. However, Christ’s use of them to make disciples of all nations remains a model of how great teachers produce other great teachers.
No matter how great our earthly teachers may be, they will err. We will have to weigh their words against the Spirit-inspired teachings of the Apostles and prophets. But we dare not think we can ever reach a point where we cannot benefit from the teaching of others. Great teachers who are faithful to God’s Word are a blessing to God’s church. He will use them to build us up so that we can build up other.”
