Speaking with one of the most respected mission workers in Germany, we were told that the theology of MacArthur is wrecking havoc in the churches in that country. You ask what specifically is the problem? The answer would be "all of the above." That is, so much that he teaches leads many astray, especially his book concerning salvation as found in the Gospels.
Many times in the past, MacArthur has had to back-track his views, realizing that what he teaches is not right. Many tell us that confusion reigns in the congregations in California. One can still depend on the great older dispensational teachers of the past. Many of the more recent dispensational teachers cannot be depended on. MacArthur claims to be dispensational but many but many scholars doubt this as true. MacArthur blasts away at Lewis S. Chafer in many of his books. He does not seem to understand what dispensationalism is all about.
Be careful what you read and depend on. I suggest my book Classical Hermeneutics published by Kregel. It will help keep your mind straight and on the biblical narrow path! --Dr. Mal Couch (3/12)
