In the quarter century after the death of the apostle Paul, heresies came in to damage the church. To counter these heresies, the apostle John began writing his books. One was a Gospel, three were Epistles, and the last was Revelation. As we study John’s writings, we will see that John was mending what was damaged. Paul completed the revelation in the Bible, but before too long there needed to be a mending ministry. Just as mended fabric is often stronger than the original, so it was with the writings of John. Certain points in the mending ministry of John are stronger than the points in the completing ministry of Paul, and The Mending Ministry of John considers John’s writings from this perspective.
