I knew with certainty that Calvinism as portrayed by the TULIP was false 40 years ago and have seen nothing to change my mind since. The greatest testimony against it are the thousands of good, fundamental, Bible-believing churches that are missions-supporting, faithfully witnessing to the saving Blood of Jesus Christ all around the world.
The rest of you can have your formalistic, high-church, ecclesiastical cemeteries . . . I'll take Jesus Christ--and Him crucified.
