An Epistle to John Hagee is a polemic based on John Hagee's Jerusalem Countdown, which blames the Christians and baffles the Jews. Those who hold on to the testimony of Jesus Christ cannot approve certain things found in the book Jerusalem Countdown. After finding out that many things written in this book were not written according to the truth of the gospel, An Epistle to John Hagee was written in the defense of the gospel of Jesus Christ.
