Revelation is a revealing look at heaven and earth from the divine perspective. It is a special style of literature (this partial recording of Sept 23rd sermon covers that point-see "Sermons in Print" in right hand column for written manuscript). In it, John shows us both the supremacy and the sacrifice of Christ, and exhorts us to perseverance in faith and to keep the perspective of faith, particularly in time of trial.
