Revelation 4:1
1:After this I looked, and, behold, a door was opened in heaven: and the first voice which I heard was as it were of a trumpet talking with me; which said, Come up hither, and I will shew thee things which must be hereafter.
[4:1 The phrases after this and things which must be hereafter move to the future -- beyond the age of the church. The door signifies entrance by the way of revelation into heaven. Chapters 4 and 5 picture a heavenly scene. The command Come up hither probably does not refer specifically to the Rapture, but rather to the change in scene for John. The trumpet signifies an authoritative voice.]
