The question that every church growth expert asks at this point is, "what were they doing in Jerusalem that we can replicate here to get the same results?" I can see the book now: 4 Steps to Add 3000 to Your Church in One Day. But we must remember that God's name is "Creator" and not a "duplicator" therefore, our goal cannot be to pursue the results God had for them then, but rather for God to unlock the potential God has for us now. With that being said the life of the Jerusalem church gives us a framework for what should guide us to create the best environment for the Holy Spirit to unlock and unleash our redemptive potential.
