Hey all,
It seemed a really good down-to-earth study on evangalism, and the questions it poses apply not only to adult new believers, but to believers who have been christians from childhood. It's 'Rick Warren approved', but its by a team of other authors - brett & dee eastman, etc.
Upon some google browsing, it seems like the series is no longer in print, but there are still copies floating around that are available to buy. (softcover, as well as ebooks).
