...it may seem that 4 walls and a roof sights about sanctuary slipped out the door. ...
You also understand that ALL these matters from the Old Testament spoke of JESUS? Not 4 walls and a roof temple? ...
The Heavenly is far greater than the "pattern" of course [and who is saying otherwise?], even as the real vehicle is greater than the model toy whose image it is made after, but the "pattern" is made after the Heavenly none the less...
...and so, while the "pattern" had many artwork of "Cherubims" on walls, which surrounded God:
Moreover thou shalt
make the tabernacle with ten curtains of fine twined linen, and blue, and purple, and scarlet:
with cherubims of cunning work shalt thou make them. Exodus 26:1
And thou shalt make a vail
of blue, and purple, and scarlet, and fine twined linen of cunning work:
with cherubims shall it be made: Exodus 26:31
And every wise hearted man among them that wrought
the work of the tabernacle made ten curtains of fine twined linen, and blue, and purple, and scarlet:
with cherubims of cunning work made he them. Exodus 36:8
And he made a vail
of blue, and purple, and scarlet, and fine twined linen:
with cherubims made he it of cunning work. Exodus 36:35
And
he carved all the walls of the house round about with carved figures of cherubims and palm trees and open flowers,
within and without. 1 Kings 6:29
The two doors also
were of olive tree; and
he carved upon them carvings of cherubims and palm trees and open flowers, and
overlaid them with gold, and spread gold upon the cherubims, and upon the palm trees. 1 Kings 6:32
And
he carved thereon cherubims and palm trees and open flowers: and
covered them with gold fitted upon the carved work. 1 Kings 6:35
He overlaid also the house, the beams, the posts, and
the walls thereof, and the doors thereof, with gold; and graved cherubims on the walls. 2 Chronicles 3:7
And
it was made with cherubims and palm trees, so that a palm tree
was between a cherub and a cherub; and every cherub had two faces; Ezekiel 41:18
From the ground unto above the door were cherubims and palm trees made, and
on the wall of the temple. Ezekiel 41:20
And there were made on them, on the doors of the temple, cherubims and palm trees,
like as were made upon the walls; and
there were thick planks upon the face of the porch without. Ezekiel 41:25
...yet, in the real Heavenly Sanctuary, God is surrounded by real Angels/Cherubims, even ten thousand times ten thousand and thousands of thousands:
And he said,
The LORD came from Sinai, and
rose up from Seir unto them;
he shined forth from mount Paran, and
he came with ten thousands of saints: from his right hand
went a fiery law for them. Deuteronomy 33:2
The chariots of God are twenty thousand, even thousands of angels: the Lord is among them,
as in Sinai,
in the holy place. Psalms 68:17
A fiery stream issued and came forth from before him:
thousand thousands ministered unto him, and ten thousand times ten thousand stood before him: the judgment was set, and the books were opened. Daniel 7:10
And Enoch also, the seventh from Adam, prophesied of these, saying, Behold,
the Lord cometh with ten thousands of his saints, Jude 1:14
And I beheld, and I heard
the voice of many angels round about the throne and the beasts and the elders: and the number of them was ten thousand times ten thousand, and thousands of thousands; Revelation 5:11
...thus we see that the OT "pattern" Sanctuary, given by God Himself, is again very relevant to Revelation...
...Jesus is standing amidst the 7 Candlesticks... which is found in the Holy Place of the Sanctuary...
...and as one moves through Revelation, we see further language of the Sanctuary, not only in items/furniture/elements [door, candlesticks, Throne, incense, altar, Ark, Commandments, etc, even of the very events also], but also of its religious Calender, as seen in
Leviticus 16, 23, etc...
...but the very Structure of Revelation itself is given in the pattern of the 7 Branch Candlestick...
