"God is like a drug, a high, [I] can't wait for the next hit." This direct quote from a megachurch member speaking about his experience of God might be dismissed as some sort of spiritually-induced drug riff. However, according to the research in this book, it was not only sincere, but a deeply felt, and sought-after sensibility. Megachurch attendees desire this first-hand experience of God, and many report finding it in their congregations.

High on God gives the first robust and plausible explanation for why megachurches have conquered the churchgoing market of America. Without condescension or exaggeration, the authors show the genius of megachurches: the power of charisma, the design of facilities, the training of leaders, the emotional dynamics, and the strategies that bring people together and lead them to serve and help others. Using Emile Durkheim's concept of homo duplex, the authors plot the strategies that megachurches employ to satisfy the core human craving for personal meaning and social integration, as well as personal identity and communal solidarity. The authors also show how these churches can go wrong, sometimes tragically so. But they argue that, for the most part, megachurches help their attendees find themselves through bonding with and serving others.
