As far as I had been able to gather from my Southern Baptist upbringing and Evangelical education, the meaning of life was to get people saved. My questions about this began when someone at church or school said the point of everything was to share the gospel. Evangelism was, it seemed, the chief end of man. Here my analytic side kicked in. What would happen if everyone became a Christian? Or what if a group of Christians were permanently stranded on a desert island? Would there be no purpose left for existence?

I was trying to understand the difference between Christianity and a pyramid scheme.
