Revelation 1:9,10

John

John was more than just a brother in Christ. He was also one going through the extreme distress of persecution. He may have been banished to the Isle of Patmos because of his continued preaching about Jesus our Lord. John indicates that he and the brethren from Asia were already in the kingdom of Jesus Christ, not looking forward to its coming (Colossians 1:13). Notice that he writes as if his time on Patmos was in the past in Revelation 1:9, so it may be that a part of this book was written after he left the island. Another part of the revelation may have been written while John was seeing it (Revelation 10:4).

McCord says, "It so happens that the word "Lord's" (Kuriakes, pertaining to the Lord) appears only twice in the New Testament, once in referring to the Lord's supper (1 Corinthians 11:20), and once in referring to the Lord's day (Revelation 1:10). Apparently these two, the supper and the day, belong together." John would have been in the spirit of mind so important for worship (John 4:23-24). However, it seems likely that he is here telling us that he was receiving a revelation from the Holy Spirit (4:2). Trumpets were used to direct troops in battle, so a voice like a trumpet would seem to be a commanding, or authoritative one.
