The God Who Advances the Gospel Through His People
If a seminary graduate is of average gifts, we think he should pastor a church. If he has above average gifts, we think he should pastor a large church. But if he has exceptional gifts, we think he should teach in seminary. I say in schools of theology that this is not the way it should be. In my view, the worst should teach, the more gifted men should pastor churches, and the very best should be missionaries. Paul and Barnabas were the best and they were missionaries.
