There is a difference between teachers and mentors. The first add information to the ignorant in hopes they will retain facts. But most facts are practically useless. We sense this by about the third grade. We say we’re never going to need most of this knowledge, and we’re usually right. Mentors are masters of subtraction. They distill knowledge into wisdom. Most teachers (like salesmen) tell you what to do, but mentors tell you what not to do. There is a fine distinction between useful and useless information. It takes a wise mentor to help us sort out all the things we could know (or memorize), but don’t need to. The most successful people know where to find the information, or at least who to call. They don’t clutter their minds. The Apostle Paul was a master at simplifying his life, both physical and spiritual. He tells the Philippians he had one thing. When you find a person who has mastered living with one thing in mind, and that one thing is Christ likeness, then you have found a useful person to have around. True mentors teach us how to preserve a pure and simple devotion to Christ in a complex world.
