In this study we discover Jesus addressing John in a vision; he is revealing to John prophecies regarding the time John lived in, and the times that would come; which is our time. In addition to the prophecies being revealed; the Lord clearly communicated to John that the time was at hand; meaning, the prophecies given to John had already started. These are not determinations; rather, these are written scriptures;
Rev 1:3 Blessed is he that readeth, and they that hear the words of this prophecy, and keep those things which are written therein: for the time is at hand.
Rev 1:19 Write the things which thou hast seen, and the things which are, and the things which shall be hereafter
John was instructed to write letters to the Seven Angels of the Seven Churches. When viewing the letters it is clear that the Lord desired that all be ready; making necessary corrections as outlined. Finally, each letter ends with a promise to the one who makes those necessary changes.
