Pastor John MacArthur recently had knee replacement surgery. Unfortunately, there were a few complications that left him bedridden for several months. It was during this time that he viewed a considerable amount of "Christian" television. An experience that he would describe as more painful than the knee surgery itself. The end result of his suffering is a two-part series titled, Toxic Television: A Biblical Answer to the Prosperity Gospel.
These are very important issues facing the church. Pastor MacArthur lays out in no uncertain terms why the prosperity gospel is a false and dangerous teaching. The audio is linked below; you can also read the transcripts or download the sermons for free at GTY (also linked below).
