Heavenly Sanctuary:
[It was] therefore necessary that the patterns of things in the heavens should be purified with these; but the heavenly things themselves with better sacrifices than these. Hebews 9:25
Sanctuary, Moses Shown The Pattern Of The Heavenly
During the EXODUS EVENT, GOD gave Moses a vision of the Heavenly Sanctuary to "pattern" the Earthly after it.
ACCORDING TO ALL THAT I SHEWED THEE, [AFTER] THE PATTERN OF THE TABERNACLE, AND THE PATTERN OF ALL THE INSTRUMENTS thereof, even so shall ye make [it].Exodus 25:9
And look that thou MAKE [THEM] AFTER THEIR PATTERN, which was SHEWED THEE IN THE MOUNT.Exodus 25:40
The EARTHLY SANCTUARY was the "pattern"/"shadow" of the HEAVENLY SANCTUARY where GOD dwells in Heaven.
Now of the things which we have spoken [this is] the sum: WE HAVE SUCH AN HIGH PRIEST, WHO IS SET ON THE RIGHT HAND OF THE THRONE OF MAJESTY IN THE HEAVENS;Hebrews 8:1
A MINISTER OF THE SANCTUARY, AND OF THE TRUE TABERNACLE, WHICH THE LORD PITCHED, AND NOT MAN.Hebrews 8:2
For EVERY HIGH PRIEST IS ORDAINED TO OFFER GIFTS AND SACRIFICES: wherefore [it is] of necessity that THIS MAN HAVE SOMEWHAT ALSO TO OFFER.Hebrews 8:3
For if he were ON EARTH, he should not be a priest, seeing that there are PRIESTS that offer gifts according to the law:Hebrews 8:4
WHO SERVE UNTO THE EXAMPLE AND SHADOW OF HEAVENLY THINGS, as Moses was admonished of God when he was about to make the tabernacle: for, See, saith he, [that] thou make all things ACCORDING TO THE PATTERN SHEWED TO THEE IN THE MOUNT.Hebrews 8:5
And the TEMPLE OF GOD WAS OPENED IN HEAVEN, and there was seen in his TEMPLE THE ARK OF HIS TESTAMENT: and there were lightnings, and voices, and thunderings, and an earthquake, and great hail.Revelation 11:19
What do you suppose is in that Ark in Heaven? HIS very Ten Commandments.
Why do we need CHRIST JESUS as our Great High Priest in the Heavenly as our Mediator, our intercessor?
What is HE doing there?
What is sin? [1 John 3:4]
It has been shown to you from Revelation 14:6-12, in the the "Everlasting Gospel" does indeed contain the Ten Commandments. The message goes forth to "Fear GOD":
Therefore thou shalt keep the commandments of the LORD thy God, to walk in his ways, and to fear him. Deuteronomy 8:6
Ye shall walk after the LORD your God, and fear him, and keep his commandments, and obey his voice, and ye shall serve him, and cleave unto him. Deuteronomy 13:4
Let us hear the conclusion of the whole matter: Fear God, and keep his commandments: for this [is] the whole [duty] of man. Ecclesiastes 12:13
The word "man" is "adam".
Within the "Everlasting Gospel" message that goes forth to the whole world, it contains the longest text in Revelation which is quoted from Exodus 20:11. - the 4th Commandment.
You cannot have Grace without Law. There is no need of Grace unless there is a Law that has been transgressed. That very same Law [Ten Commandments] must still be in existence to this very day in order for anyone to have need of the Grace of God.
Why does anyone need a Gospel if there is no longer a Law to transgress?
Where there is no Law, there is no transgression. [Romans 4:15]
No transgression, there is then no more sin.
No sin, no need of the Saviour Christ Jesus or His atoning Blood. None whatsoever.
