The Book of Revelations is the last book of the New Testament. It contains visionary descriptions of heaven and of conflicts between good, evil and of the end of the world. The book is attributed to Saint John the Apostle.
Revelation offers comfort and encouragement to Christians of all ages that God is firmly in control. When the time is right, the forces of evil that seem to dominate our world will be utterly destroyed, and God's eternal kingdom will come into its fulfillment. In particular, John's vision offered encouragement and comfort to the persecuted Christians that their suffering was not in vain. God would surely triumph and destroy the evil that was the source of their persecution.
