The crystal firmament in Ezekiel’s vision and the “sea of glass” in Revelation convey a related picture of God’s heavenly glory, but shown from different points of view. In prophetic visions, the spatial words “above,” “below,” and “before” do not contradict one another: they depend on who exactly sees the heavenly throne and from which side the person describes what was seen.
What exactly did Ezekiel see?
In the first chapter of the book of Ezekiel, the prophet sees four living creatures, which biblical tradition associates with cherubim. They do not move independently, but by the action of God’s Spirit. Above them stretches something like radiant, transparent crystal. This is not the ordinary atmospheric sky, but a symbolic depiction of the heavenly sphere where God’s presence is revealed.
“The likeness of a firmament above the heads of the living creatures was like the color of an awesome crystal, stretched out over their heads.” Ezek. 1:22
It is important to read this text in its immediate context. Ezekiel twice emphasizes that the creatures are under the authority of the Spirit, and do not carry God mechanically or independently of Him.
“Wherever the spirit wanted to go, they went, because there the spirit went; and the wheels were lifted together with them, for the spirit of the living creatures was in the wheels.” Ezek. 1:20
After describing the firmament, the prophet sees an even higher reality: above the crystal expanse there is a throne, and on the throne is the likeness of a Man. Thus, the order of the vision is this: the living creatures below, above them the firmament, and above the firmament God’s throne.
“And above the firmament over their heads was the likeness of a throne, in appearance like a sapphire stone; on the likeness of the throne was a likeness with the appearance of a man high above it.” Ezek. 1:26
Is this firmament identical to the sea of glass?
It should not be claimed that Ezekiel literally calls this object a “sea of glass.” He uses the image of a firmament resembling crystal; John speaks of a sea of glass, like crystal. Yet there is a clear kinship between the visions: in both cases there is God’s throne, heavenly living creatures, and a shining crystal-clear expanse.
“Before the throne there was a sea of glass, like crystal. And in the midst of the throne, and around the throne, were four living creatures full of eyes in front and in back.” Rev. 4:6
These texts do not necessarily give us a technical blueprint of heaven. Apocalyptic language uses images understandable to people in order to convey the majesty, purity, unapproachability, and perfect order of God’s throne. Crystal, sapphire, and glass emphasize light and transparency. Before God there is no darkness, deceit, or chaos.
From an Adventist perspective, such visions also harmonize with the biblical teaching about the real heavenly sanctuary. The earthly sanctuary was a pattern of the heavenly one, but it cannot fully reproduce its glory. Ellen G. White repeatedly emphasized that Christ’s ministry in the heavenly sanctuary is the real foundation of our hope, though human language cannot fully describe heavenly glory.
Why is the firmament above their heads in Ezekiel?
Because Ezekiel describes the position of the firmament in relation to the living creatures. The cherubim are below the throne; above their heads is the crystal expanse. That is why the text does not say that it is under their feet. The firmament is a boundary or shining surface between the creatures and the throne, which the prophet sees above it.
This is especially important for reading verses 19–20. When the creatures move, the wheels move beside them; when the creatures rise, the wheels also rise. But the firmament is not described as ground on 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 texts?
Exodus 24 describes a different angle. Moses, Aaron, Nadab, Abihu, and the elders of Israel look upon the manifestation of God from a human, earthly perspective. They see what is called something like a sapphire pavement under God’s feet.
“And they saw the God of Israel. And there was under His feet as it were a paved work of sapphire stone, and it was like the very heavens in its clarity.” Exod. 24:10
There is no contradiction here with Ezekiel. What is above the heads of the cherubim, can at the same time be under the feet of God’s throne. In other words, the same radiant heavenly expanse is described in relation to different persons: for the cherubim it is above them, and in relation to God it is beneath Him. In Revelation, John describes it as lying before the throne. These are different directional descriptions of one heavenly scene, not three incompatible objects.
Conclusion and practical application
Ezekiel 1:22 through 1:20 should be read as a single vision of God’s throne, not as an attempt to measure heavenly space with human coordinates. Ezekiel’s crystal expanse, the sapphire purity in Exodus, and John’s sea of glass share a common purpose: to show the holiness, clarity, and supreme authority of God. For the believer, this means that above the movement of history, the anxieties, and the chaos of the world stands the throne of the Lord. Apply this truth practically today: in prayer, hand over your uncertainty to God and consciously submit your decisions to Him, remembering that His Spirit leads His people not chaotically, but wisely and purposefully.
