Paul again! This time, he is writing a letter to his star pupil, a young man he is mentoring to be a pastor. In this section, Paul is modeling the humility that often defines his writing, and also casts a picture of what Timothy's job is going to look like. It's no pleasure cruise, he will definitely encounter opposition. There will also come others who try to make the Gospel about something other than Jesus, but not Timothy: he must keep Jesus central.
