According to Paul's letter to the Hebrews, and OT testimony, the entire sanctuary of the OT, including the later temples in Jerusalem, and all the furniture inside, were copied from the pattern God gave Moses, forming a miniature replica of the original sanctuary in heaven wherein is God's throne.
The Ark that resided in the earthly sanctuary was hidden away in a cave by Jeremiah before the invasion by Babylon . That ark of the covenant remains hidden, and would still contain the original tables of stone.
So my question remains unanswered. What is inside the ark of the testimony in heaven? It is called the ark of the testament... What is the testament?
The are no unanswered questions. The earthly tabernacle
was a pattern of the tabernacle in heaven.
The Testament that was in the ark of the testament
in the earthly tabernacle is
the 10 Commandments representing all the law - and it's a testimony against us - see Jeremiah 31:31-33.
The nations seen being judged in the 7th trumpet are judged by the 10 commandments because without the blood of Christ covering "the mercy seat" there is no forgiveness for sins - which is the transgression of the law.
Exodus 20:18: Receiving of the testament:
Thunderings and lightnings and the noise of the trumpet:
"And all the people saw the thunderings, and the lightnings, and the noise of the trumpet, and the mountain smoking: and when the people saw it, they removed, and stood afar off."
Revelation 11:19 (7th trumpet). Ark of the testament seen in heaven:
Lightnings, and voices, and thunderings, and an earthquake, and great hail:
"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 8:5 (7th seal):
Voices and thunderings and lightnings and an earthquake:
"And the angel took the censer and filled it with fire from the altar, and cast it into the earth. And voices and thunderings and lightnings and an earthquake occurred."
Rev 16:17-18 (7th vial):
Voices and thunders and lightnings:
"And a great voice came out of the temple of Heaven, from the throne, saying, It is done! And voices and thunders and lightnings occurred."
Revelation 15: The temple of the tabernacle of the testimony was opened in Heaven (verse 5):
* Four beasts
* sea of glass
* those who had gotten the victory over the beast, and over his image, and over his mark, and over the number of his name, are seen standing on the sea of glass, having the harps of God.
Revelation 4:
"lightnings and thunderings and voices":
* 24 elders.
* clothed in white raiment.
* crowns of gold on their heads.
* sea of glass.
* Four beasts.
* Out of the throne proceeded lightnings, thunderings, and voices.
Sealed seven times.
7th TRUMPET
"And the temple of God was opened in Heaven, and there was seen in His temple the ark of His covenant,
and occurred lightnings and voices, and thunders and an earthquake, and a great hail." (Revelation 11:19).
7th PLAGUE
"And the seventh angel poured out his vial into the air. And a great voice came out of the temple of Heaven, from the throne, saying, It is done!
And voices and thunders and lightnings occurred. And there was
a great earthquake, such as has not been since men were on the earth, so mighty and so great an earthquake." (Revelation 16:17-18).
7th SEAL (a scroll is only sealed AFTER its contents were already written down)
"And the angel took the censer and filled it with fire from the altar, and cast it into the earth.
And voices and thunderings and lightnings and an earthquake occurred."
The entire scroll now unrolled, because all the seals had been loosened:
"And the seven angels which had the seven trumpets prepared themselves to sound." (Revelation 8:5-6).
