Constituencies of Evangelism

I just finished reviewing Walter Brueggemann's book, Biblical Perspectives on Evangelism: Living in a Three-Storied Universe, for my doctoral work at Truett Seminary/Baylor Univeristy. I found it to be helpful in many ways but was very thankful for his notion of constituencies of evangelism. He says that the constituencies are: "outsiders, jaded insiders, and children-becoming-adults" (p. 12). I think of these as: the un-churched, the de-churched, and the pre-churched. I am wonderding how your disciple-making methods change when you are ministering to persons in these different groups. For example -

How do you share the gospel with those totally outside the faith community?

How do you share the gospel with those that have left the church?

How do you seek to prevent "defection" and its evil twin "false confession?" Can these be prevented?

How do you share with children?

Note: "you" = the church you serve.
