John White has extensively interviewed many people, including those from John Wimber's Vineyard Christian Fellowship. His years of work as a psychiatrist and as a missionary in the Third World qualify him in a special way to analyze the experiences described in this book. In addition he has thoroughly studied revivals of the past, highlighting the differences and the similarities to what is happening today.
As always, John White remains thoroughly biblical as he handles many controversial topics. The result is a book full of practical wisdom and remarkable insight with conclusions that are fresh and surprising.
