Designing Discipleship Systems: from the Introduction 1.1
QUOTE In the beginning, west of Eden, humanity began to fulfill the command of God: “be fruitful and multiply.” God’s creation is continually fruitful in a continually changing environment. To adapt and be fruitful is natural to all creation.
In the beginning, north of Calvary, the disciples began to fulfill the command of Jesus Christ to be fruitful and multiply:
And Jesus came and said to them, “All authority in heaven and on earth has been given to me. Go therefore and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit, teaching them to observe all that I have commanded you; and lo, I am with you always, to the close of the age” (Matthew 28:18-20) .
In the following twenty centuries the pace of change has accelerated as the population of the world has increased. Each new generation of Christians has flourished relative to their obedience to everything that Jesus commanded. As Donald McGavran said, “It is God’s will that his Church grow, that his lost children are found”  The foundational principle of church growth is “Thy will be done” (Matthew 6:10). The Great Commission is more than a principle; it is a pattern for the Church of Jesus Christ to obediently practice in order to fulfill God’s will to be fruitful and multiply.
