"On the basis of these two instances - Jesus at Jordan and the Church at Pentecost - the nature of a true Spirit explosion can be tested by two criteria. 1. There should be evidence of an unsettling of the superficial ... 2. There should be an experience of fulfillment and loveliness worthy of the signature of the Creator".
Jack Hayford in "The Charismatic Explosion in the Local Church" - New Wine Magazine - July 1975 - CGM Ministries - (p10).
