Comiskey's thesis is that reproduction or church multiplication is critical to all effective church planting. Thus, church planting must be simple enough to keep the process going.

The first section lays out the Biblical basis for church planting. The book moves from the Biblical basis to the contemporary scene, showing why church planting is absolutely essential to keep up with the population growth. Comiskey also highlights the characteristics which make a modern day church planter successful. Comiskey draws from practical experiences to help those who are in the battle or are considering church planting.

The second section goes into detail about church planting strategies, namely the cell church strategy and house church planting. The reader is not just given information about different church planting approaches but is also shown how to use them.

Comiskey's book is a must-read book for those interested in establishing Christ-honoring, multiplying churches.
