We are now experiencing the unique ministry of John the Mender, the apostle whose particular function it was to call men back to fundamentals. This was foreseen, in figure, in the act John was performing when he was called by Christ, for he was found mending his nets. The ministry of a mender is very much needed in any hour of weakness and attack. This is why the Holy Spirit chose the Apostle John to be the last writer of Scripture. His writings came at a time when the Church had begun to be infiltrated by various false concepts and ideas, and strong persecution had arisen.
