Ray mined the deep truths of the Apostle John's First Epistle in a series of 34 sermons. "Peter...was called as a fisherman, and we are told in the Gospels that the moment of his call occurred when the Lord found him casting a net into the sea. That work of fishing for men is characteristic of the Apostle Peter. He is always beginning things, initiating new programs. To him was committed the keys of the kingdom by which he could open the door to the new things God was introducing. On the day of Pentecost he used one of those keys and as a result caught 3,000 fish in his gospel net. You find that characteristic of this man all through his written ministry. To the Apostle Paul, however, was committed a different task. When Paul was called he was a tentmaker. He made things. He built things. This, then, was the ministry committed to the Apostle Paul. He is a builder. He not only lays the foundation but he builds upon it. He calls himself "a wise master-builder" and to this man, this mighty Apostle, was committed the task of building the great doctrinal foundation upon which the Christian faith rests. But John is different than both of these. When John was called he was found mending his nets. John is a mender. His written ministry comes in after the church has been in existence for several decades and at a time when apostasy had begun to creep in. There was need of a voice to call people back to the original foundations and that is the ministry of the Apostle John. He calls men back to truth. When we begin to drift, when some false concept creeps into our thinking or into our actions, it is John who is ordained of the Lord to call us back, to mend the nets and to set things straight."
