The seven days represent seven thousand years - with the seventh being a type of the sabbath, or Gods' "day of rest".
There is also a type for the seven days as the "Seven Church Ages", which span Christ's first coming to His second coming.
Each age had an alloted messinger with a message from God for the people of that age.
The Gentile Church Ages are over at Christ's return - when He is "revealed" from heaven as the Son of Man.
At this time He is the one in Rev. 5 who is found worthy to take "The Book" and open the seals thereof......When He is revealed as the Son of Man it is a secret coming.
The Voice of God calls the names of His elect by the revelation of the mysteries contained within the seven sealed book which have been hid from Mankind since before the foundation of the world, to be revealed at His coming.
This revelation of Himself, - for He is "The Word" is the Shout,...the message to gather together the elect, The Voice of the Arch-Angel.....the message of this last messinger to quicken the Bride and trim her lamps, making herself ready by puting on her wedding garment, Christ the revealed Word of God, the Bridegroom, and The Trumph, the trumpet calling the elect to the wedding supper.
There is a type of an Eighth day, beyond the seven.
After the Seven church ages are over, and Christ rises from the mercy seat as interceser where He has been for nearly 2000 years, He returns to do this work as the Son of Man.
There remains a maturing period for the bride, a rapturing process in which the "wheat" must lay in the presence of "The Son" to ripen.
There is a type for this "Eighth day" in the Feast of Tabernacles in the old testement.
In the Feast of Tabernacles there where eight feast days, not seven.
This speaks of an "Eighth Day", after the seven church ages are over......a "Bride Age".
The number eight if layed sideways is the symbol for infinity, and those who enter into "His" rest, the Millineum, are "eternal".
The Bride, the many-membered body of Christ, taken from out of each age.
They enter into an eternal land, a kingdom that has no end.
