As for Ezekiel’s vision he’s seeing the same thing John sees when he’s taken into heaven Ezekiel is seeing the throne of God from earths view John from heavens view
In chapter one he sees the throne of God
“… I was among the captives by the river of Chebar, that the heavens were opened, and I saw visions of God.
And I looked, and, behold, a whirlwind came out of the north, a great cloud, and a fire infolding itself, and a brightness was about it, and out of the midst thereof as the colour of amber, out of the midst of the fire.
Also out of the midst thereof came the likeness of four living creatures. And this was their appearance; they had the likeness of a man. As for the likeness of their faces, they four had the face of a man, and the face of a lion, on the right side: and they four had the face of an ox on the left side; they four also had the face of an eagle.
And the likeness of the firmament upon the heads of the living creature was as the colour of the terrible crystal, stretched forth over their heads above. ( Ezekiel is below the firmament on earth looking up )
And there was a voice from the firmament that was over their heads, when they stood, and had let down their wings. And above the firmament that was over their heads was the likeness of a throne, as the appearance of a sapphire stone: and upon the likeness of the throne was the likeness as the appearance of a man above upon it. And I saw as the colour of amber, as the appearance of fire round about within it, from the appearance of his loins even upward, and from the appearance of his loins even downward, I saw as it were the appearance of fire, and it had brightness round about.
As the appearance of the bow that is in the cloud in the day of rain, so was the appearance of the brightness round about. This was the appearance of the likeness of the glory of the LORD. And when I saw it, I fell upon my face, and I heard a voice of one that spake.”
Ezekiel 1:1, 4-5, 10, 22, 25-28 KJV
A closer look John is taken up into heaven so the firmament looks like a crystal sea because he’s above it
“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. And immediately I was in the spirit: and, behold, a throne was set in heaven, and one sat on the throne. And he that sat was to look upon like a jasper and a sardine stone: and there was a rainbow round about the throne, in sight like unto an emerald.
And before the throne there was a sea of glass like unto crystal: and in the midst of the throne, and round about the throne, were four beasts full of eyes before and behind. And the first beast was like a lion, and the second beast like a calf, and the third beast had a face as a man, and the fourth beast was like a flying eagle.”
Revelation 4:1-3, 6-7 KJV
John is revealing what Ezekiel saw the likeness of
“the likeness of a throne with someone like a man upon it “ is revealed by John
“and in the midst of the seven candlesticks one like unto the Son of man, clothed with a garment down to the foot, and girt about the paps with a golden girdle. His head and his hairs were white like wool, as white as snow; and his eyes were as a flame of fire; and his feet like unto fine brass, as if they burned in a furnace; and his voice as the sound of many waters. And when I saw him, I fell at his feet as dead. And he laid his right hand upon me, saying unto me, Fear not; I am the first and the last: I am he that liveth, and was dead; and, behold, I am alive for evermore, Amen; and have the keys of hell and of death.”
Revelation 1:13-15, 17-18 KJV
and when John is taken up into heaven it’s revealed who the one like the son man on the throne is
“And I beheld, and, lo, in the midst of the throne and of the four beasts, and in the midst of the elders, stood a Lamb as it had been slain, having seven horns and seven eyes, which are the seven Spirits of God sent forth into all the earth.”
Revelation 5:6
the imagery seems otherworldly it’s a spiritual vision peering into the heavenly realms in Christ
