I was once told that as a pastor, my job was to work myself out of a job. Obviously, that's not entirely true. The sheep always need a shepherd and that's what God has called pastors to do. But the point is that pastors ought to be training their congregations to do the work of the ministry (Eph. 4:11-12), and the hope is that they become so effective doing that ministry, that the "doing ministry" part of the pastor's job is being done by the congregation, not just the pastor.
The hope is also that we train our people is such a way when it comes to Bible Study that they aren't dependent on the pastor alone to get their "meat" from God's Word, but learn to study and meditate and learn for themselves.
Pastor John Piper is beginning a new project for that very purpose. "Look at the Book" is an online tool where Pastor Piper takes a text, outlines it, examines it, mines it, and in the process shows us how to do the same thing. This isn't meant to replace our own study, but teach us how to study. This is a very promising and exciting project.
Here is the introductory video and one of the first "sessions." I encourage you to check this resource out.
