Teachers Passé?

In 2:27, John unexpectedly writes that with the Holy Spirit, a teacher is no longer necessary. This is a scary thought for me, since I work full-time as a teacher.

And James writes that teachers will be judged more harshly (3:1).

Maybe what John means is that with the Holy Spirit, we don't need a personal, human "tutor of truth" with us 24/7. We simply need to listen to the Holy Spirit's guidance living within us.
