Edit: One idea I am tossing around is that after doing a lesson at the beginning on the general idea of "leadership", is to then take different qualities/characteristics of leaders and use them in subsequent lessons. For example, if "courage" is a characteristic, I would use that with a lesson on Esther. What are your thoughts?
Update: I've made this into an 8-week study. Some of the topics are "Callings, Gifts, & Gender", "Prophets", "Jesus & Women", "The New Testament Church", "Leadership", "Recap and Reflection". Two of the others I don't have lesson titles for yet as I'm not totally sure what I'm doing in them. But progress is being made!
