Chris Rosebrough highlighted a talk given by Phil Johnson at the Strange Fire Conference in Southern California this last October 17th.
The name of the conference "Strange Fire" is a reference to Leviticus 10:1-6 where Aaron's sons, Nadab and Abihu, presumed to make their own way of worship before God contrary to what God had specifically commanded under the First Covenant. The conference comes from the background of the Reformed churches and is an effort on their part to evaluate the current theological claims and practices of mainly Reformed pastors, congregations, and church bodies.
The talk is well worth taking the time to listen to. Many of the points of criticism that Johnson brings up to show where the modern Charismatic movement is un-biblical and dangerous are precisely where Lutherans and other Christians who neglect reading Scripture are vulnerable.
