Sorry for long delay between posts. I have been holidaying and being busy with things and begetting a little daughter (Esther Kate) and other lam excuses...
I heard a cool startegy for small group Bible study writing just recently. It's a compromise between the convenience of using pre-written Bible studies and writing your own.
Whoever is in charge of writing Bible studies doesn not prepare a complete Bible study package. Rather, they prepare at most one double-sided A4 page of notes on the passage including exegesis, key turning points, suggestions for leading, ideas for application.
This then leaves it up to the individual study leader to decide what to do with this. They could use these notes to help them as they lead a loose discussion. they could use these note to write a Bible study. Overall it is more 'manpower' (since each leader has to develop this page of notes in some way). However it is less time investment for the Bible study write.
Moreover, it has three advantages. First of all, it may promote a slightly higher rate of study leader preparation. After all, even with pre-written studies, the study leader is meant to spend time preparating. Perhaps it actually reduces overall work time?
Secondly, it is teaching the study leader how to think through the study leading process much more thoroughly, therefore it is training them more.
Thirdly, it prevents leaders from assuming that the entire goal of study leading is to answer the questions on the page or criticising the wording and clarity of the questions.
