Dr. Constantinou continues her study of Revelation with Chapter 4, John's visit to heaven, known as the "Throne Room" scene. There we see angels, elders, thrones, a rainbow, a sea of glass, and the lamb. What is the meaning of the imagery and the numbers? Who is on the throne? Why are the four creatures by the throne identified with the evangelists? She also addresses an important theological question: When Christ said that only the Father knows the time of His return, does this mean that the Lord is ignorant of the time of the end?
