Schwarz is the founder of an international organization that assists churches in growing. Unlike other books that state their methods, and claim them to be both biblical and universally effective, his organization takes a very statistical approach. Using a proprietary survey instrument, Schwarz surveyed tens of thousands of churches (both healthy and unhealthy, growing and declining) and analyzed the data to determine what characteristics were common among growing, healthy churches. He found 8 major characteristics – ranging from holistic small groups to empowering leadership to inspiring worship services – and then organized those characteristics to some underlying growth principles, and to a growth spiral (essentially a process of continuous improvement). As someone with a background in qualitative and quantitative research, I found Schwarz’s methods and analyses very interesting. The way he described his findings was very methodical and data-driven – something most church growth books lack. Unfortunately, the entire book is a very shallow read. Schwarz only describes his characteristics, principles, and processes at a very high level. Clearly the goal of this book is to get you interested in his organization’s total consulting package. He repeatedly refers to the NCD survey and training and program, but does not provide the full details. Unlike most Christian books that give away their secrets and methods in the hopes that they inspire churches and church leaders, and expand and impact the kingdom of God, this book hoards its knowledge. This approach turned me off completely. Unique approach, but too shallow a read to recommend.
