Jack Deere is an American charismatic pastor and theologian.
He was an associate professor of Old Testament at Dallas Seminary.
In the late 1980s, he abandoned his earlier theological position, announcing that he had experienced the charismatic gifts for himself through the ministry of John Wimber.
From 1988 to 1992 he pastored a Vineyard church, and pastored a Presbyterian church in Montana from 1994 to 1996. He remained in Montana for several years while traveling and speaking, and then moved back to the Dallas-Fort Worth Metroplex where he was pastor of Wellspring Church in North Richland Hills, a church now pastored by Michael Rowntree.
Deere's first book, published in 1993, Surprised by the Power of the Spirit, details his journey into charismatic Christianity, arguing against the cessationist position that the miraculous gifts of the Spirit have ceased. He deals with the arguments of B.B. Warfield and John MacArthur, among others. A companion book, Surprised by the Voice of God, argues for contemporary prophecy and supernatural revelation. He speaks about his experience of the Kansas City Prophets and the ministry of Paul Cain.
