DBQ: Passing the Torch

Ecclesiastes 2:18-21 speaks of the vanity of working really hard and wisely for something, and then having someone take over the work, only to make a mess of it. Many of us have had the experience of trying to pass the torch to someone, especially in ministry, and having that person drop the torch, or not grab it at all. So what can we do as Christians in ministry to make sure that the torch gets passed well? In other words, what can we do to make ministry transitions as wise and effective as possible and to avoid the vanity expressed here in Ecclesiastes?
