How does the crystal expanse in Ezekiel 1:22 relate to the sea of glass?

The crystal expanse in Ezekiel’s vision and the “sea of glass” in Revelation convey a related depiction of God’s heavenly glory, yet shown from different vantage points. In prophetic visions, directional terms such as “above,” “under,” and “before” do not contradict one another; they depend on who is seeing the heavenly throne and from what perspective they are describing what they behold.

What exactly did Ezekiel see?

In the first chapter of the book of Ezekiel, the prophet sees four living creatures, whom biblical tradition identifies as cherubim. They do not move on their own, but under the impulse of God's Spirit. Stretched out above them is something resembling radiant, transparent crystal. This is not an ordinary atmospheric sky, but a symbolic representation of the heavenly realm where God's presence is manifested.

“Over the heads of the living creatures there was the likeness of an expanse, shining like awe-inspiring crystal, spread out above their heads.” Ezek 1:22

It is important to read this passage in its immediate context. Ezekiel emphasizes twice that the creatures are governed by the Spirit, rather than carrying God mechanically or independently of Him.

“Wherever the spirit wanted to go, they went, and the wheels rose along with them, for the spirit of the living creatures was in the wheels.” Ezek 1:20

After describing the expanse, the prophet sees an even higher reality: above the crystal dome is a throne. On the throne is the likeness of a Human form. Thus, the order of the vision is as follows: the living creatures below, the expanse above them, and above the expanse stands God's throne.

“And above the expanse over their heads there was the likeness of a throne, in appearance like sapphire; and seated above the likeness of a throne was a likeness with a human appearance.” Ezek 1:26

Is this expanse identical to the sea of glass?

We should not claim that Ezekiel literally calls this object a “sea of glass.” He employs the imagery of an expanse resembling crystal; John speaks of a sea of glass, clear as crystal. Nevertheless, there is a clear kinship between the visions: in both cases, there is God’s throne, heavenly living creatures, and a radiant, crystal-clear expanse.

“And before the throne there was as it were a sea of glass, like crystal. And around the throne, on each side of the throne, are four living creatures, full of eyes in front and behind.” Rev 4:6

These passages do not necessarily provide us with a technical blueprint of heaven. Apocalyptic language uses imagery intelligible to human beings to convey the majesty, purity, unapproachability, and perfect order of God’s throne. Crystal, sapphire, and glass accentuate light and transparency. Before God, there is no darkness, deception, or chaos.

From an Adventist perspective, such visions also harmonize with the biblical teaching about the real heavenly sanctuary. The earthly sanctuary was a shadow of the heavenly, yet it could not exhaustively reproduce its majesty. Ellen White repeatedly emphasized that Christ's ministry in the heavenly sanctuary is the real foundation of our hope, even though human language is incapable of fully describing heavenly glory.

Why is the expanse above their heads in Ezekiel?

Because Ezekiel describes the position of the expanse relative to the living creatures. The cherubim are positioned beneath the throne; above their heads is the crystal dome. That is precisely why the text does not say it is under their feet. The expanse serves as a boundary or radiant platform between the creatures and the throne that the prophet sees above it.

This is especially important for understanding verses 19–20. When the creatures move, the wheels move beside them; when the creatures rise, the wheels also rise. But the expanse is not described as a ground upon which they walk. It remains above them as a sign of God's supremacy and royal presence.

Why is something similar under the feet in other passages?

In Exodus 24, a different angle is described. Moses, Aaron, Nadab, Abihu, and the elders of Israel look upon the manifestation of God from a human, earthly perspective. They see what is described as something like a pavement of sapphire stone under God's feet.

“And they saw the God of Israel. There was under his feet as it were a pavement of sapphire stone, like the very heaven for clearness.” Exod 24:10

There is no contradiction with Ezekiel here. What is above the heads of the cherubim can simultaneously be under the feet of God’s throne. In other words, the very same radiant heavenly pavement is described relative to different entities: for the cherubim, it is above them, while relative to God, it is beneath Him. In Revelation, John describes it as lying before the throne. These are different spatial perspectives describing one heavenly scene, not three incompatible objects.

Conclusion and practical application

Ezekiel 1:22 should be read as a unified vision of God’s throne, not as an attempt to map out heavenly dimensions using human coordinates. Ezekiel’s crystal expanse, the sapphire clarity in Exodus, and John’s sea of glass share a common purpose: to display the holiness, clarity, and supreme sovereignty of God. For the believer, this means that above the currents of history, the anxieties, and the chaos of this world stands the Lord’s throne. Put this truth into practice today: in prayer, surrender your uncertainties to God and intentionally submit your decisions to Him, remembering that His Spirit leads His people not haphazardly, but with wisdom and purpose.
