Bill Beckham describes how Jesus used groups of different sizes and relationships (three, twelve, seventy, and one hundred and twenty at Pentecost) to fulfill his global purpose. Beckham demonstrates how we need to relearn Christ's same relational strategy to plant churches and win a lost world for Jesus Christ. Beckham shows how many churches today have allowed an Old Testament theology to dictate their ecclesiology. He then offers practical advice and clear direction to return to the original way to live Church as an expansion movement, like Jesus did. In this book Beckham shows how the Cell Church Movement is God's answer to take the church back to a place of fruitfulness and effectiveness.
