This word -revelation- is the English way of expressing the Greek word -apocalypses,- which means, -the pulling back of a veil.- When we study in the area of the future, spiritual things that are yet to be fulfilled, we really need the Master Key, the Holy Spirit. God the Father is turning the center of worship in heaven from Himself to His Son, the Lamb, Who looks as if He has been slain, expressing the essence of Who and what God is.
