Ministry professional Allan Taylor writes to all church leaders about the crucial role that Sunday School must play in producing healthy Christians who in turn produce healthy churches. He emphasizes the value of the Sunday School model to the total church ministry for its superior ability to nurture relationships and more personally stir passion for the Great Commission across every age group.

Taylor presents the sharply focused idea that all Sunday School programs are either imploding (through directionless ineffectiveness) or exploding (thanks to visionary leadership and practicing some fundamental disciplines). As such, he guides the reader toward growth principles that must be operative for any church to begin or continue a transformational Sunday School boom.
