The same person that wrote the first epistle of John, was also the author to the second epistle, and was probably John, the disciple and son of Zebedee. He was writing to the elder elect lady and her children, which some take literally to mean a personal acquaintance, and others believe it to metaphorically represent a particular local church and congregation of members. John intended to visit his readers soon. He was pleased in their spiritual progress, but felt that special words of admonition were necessary to assure continued progress.
