Revelation 1:10

10 I was in the Spirit on the Lord's day, and heard behind me a great voice, as of a trumpet.

After giving us the purpose of the book and the greetings, John tells us that he was in the Spirit on the Lord's day.  It might refer to Saturday or Sunday but it could have deeper implications about being taken forward in time to the Day of the Lord. John hears behind him a great voice that sounded like a trumpet but before we go on to read what John saw and heard let us review the truths revealed in just the first 10 verses of Revelation chapter one.
