A cynic once asked, “What in the world are you Christians doing?” I can think of no more relevant question for the church here at the beginning of the twenty-first century. When an individual comes to Christ, they enter into the greatest task in the world. Jesus said, “Go and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit, and teaching them to obey everything I have commanded you. And surely I am with you always, to the very end of the age.” No book on personal evangelism can be approached strictly from an academic viewpoint or even from a “how-to-do-it” approach. There is always a sense of the presence of the supernatural when God allows us to be actively present when the Holy Spirit does his mighty work in the heart of someone who is responding to Christ. C.S. Lewis was correct—when an individual comes to Christ, the only and best description is joy!
