This book is about evangelism, evangelists, evangelizers, and witnesses. It is all about God's power working in and through each individual Christian. It is based on the observation that when individuals truly come to Christ in salvation, it is easy and natural for them to talk to others about the One they love. And such a person can do so without fear or training or knowledge of theology. Christians are given the natural capacity to speak of the great things God has done for them from the very moment of their salvation! They are like spiritual hurricanes. The eye, or center, of the hurricane represents a quiet and peaceful relationship believers have with Christ; then the Holy Spirit uses them and takes even their "mistakes," their so-called errors, and gives them success in evangelism. Since the Holy Spirit within is the Evangelist, there are no failures in evangelism (cf. Philippians 1:15). Success is guaranteed. The only failure is when we do not open our mouths!
