Evangelism follows patterns presented in scripture, and can be broken down into three phases: outsiders being invited inside, a jaded insider invited to a deeper level, and children becoming adults. Evangelist encounters in the Bible confronted these types and are given as models for the modern-day church to learn from. Walter Brueggemann, concerned about the issue of evangelism in the church in the 1980s, penned this book almost two decades ago, and the themes he covers are still valid.
