The book of Revelation contains God’s assurance that though we live through difficult times, God’s cause will triumph, and God will sustain his people. Revelation is God’s book of prophecy and encouragement for the New Testament age in which we live. It describes the survival and triumph of Jesus’ followers and his church through the ages even though successive empires have and continue to oppose Jesus and his people.
The textbook for the class is: Tyndale New Testament Commentaries, Volume on Revelation by Leon Morris.
