"I did not see a temple in the city, because the Lord God Almighty and the Lamb are its temple. The city does not need the sun or the moon to shine on it, for the glory of God gives it light, and the Lamb is its lamp."
— Revelation 21:22-23
Quick Answer
Most likely both: a real, physical city described using deliberately symbolic numbers and imagery. Revelation consistently uses apocalyptic language to convey real truths (compare Revelation 1:20), so its cube shape, gemstones, and impossible dimensions likely communicate perfection, security, and God’s presence (Revelation 21:16-22) rather than functioning as an architectural blueprint to be measured literally.
A Genre Question First
Before deciding whether any single detail in Revelation is literal or symbolic, it helps to remember what kind of book Revelation is. It identifies itself as prophecy delivered through vivid apocalyptic vision (Revelation 1:1-3), a genre that regularly uses symbolic numbers and images to communicate real, weighty truths, without every image functioning as a flat, literal description. John himself explains some of his own symbols directly: “The mystery of the seven stars... The seven stars are the angels of the seven churches” (Revelation 1:20), showing that Revelation’s images often stand for real realities without being literal in the most straightforward sense.
The Case for Symbolic Reading
The New Jerusalem’s measurements are a strong candidate for symbolic language. A city 12,000 stadia long, wide, and tall (Revelation 21:16), roughly 1,400 miles in every direction, would be an impossibly enormous cube by any literal architectural standard. The number twelve and its multiples appear throughout the description, gates, foundations, the number of tribes and apostles, and 12,000 is twelve multiplied by a thousand, numbers Revelation elsewhere clearly uses symbolically, such as the 144,000 (Revelation 7:4) understood by many interpreters as twelve squared multiplied by a thousand, representing the complete, full number of God’s people rather than a literal headcount.
The Case for a Real, Physical City
At the same time, Revelation is describing something John insists he genuinely “saw” (Revelation 21:2), descending to a real, renewed earth (Revelation 21:1). This is consistent with the rest of Scripture’s hope for a physical resurrection and a physical new creation, not merely spiritual metaphor detached from any real location or substance (1 Corinthians 15:42-44, Romans 8:19-23). The best reading holds both truths together: a real, physical city exists, described through symbolic numbers and images that communicate its meaning and significance rather than its precise blueprint.
What the Symbols Are Actually Saying
Read this way, the cube shape recalls the Most Holy Place (1 Kings 6:20), signaling that the entire city has become a place of direct access to God’s presence. The gemstone foundations (Revelation 21:19-20) picture indescribable beauty and value. The perfect, symmetrical dimensions picture completeness and order, nothing lacking, nothing excessive. The walls thick enough to be measured yet gates that never close (Revelation 21:12, 25) picture total security without isolation. None of this requires denying the city is real; it means the numbers are doing theological work, not merely providing measurements for a hypothetical tourist.
Why This Isn’t Evasive Interpretation
Some worry that calling any part of Scripture symbolic is a step toward not taking the Bible seriously. But recognizing genre and authorial intent is part of taking Scripture seriously, not less. Jesus himself used deliberately non-literal language constantly, calling himself a vine, a door, and bread, without anyone concluding he denied being a real person. Revelation’s original readers, familiar with apocalyptic literature, would have expected and understood this kind of symbolic communication far more readily than modern readers unfamiliar with the genre.
What Isn’t in Question
Whatever conclusions one reaches about specific numbers and images, the core realities described are not in question among faithful interpreters: a real, physical, renewed creation; God dwelling directly and permanently with his redeemed people; total security, beauty, and the complete absence of sin, sorrow, and death (Revelation 21:4). The debate over literal versus symbolic details should never obscure the settled, central hope the whole passage exists to deliver.
It is worth remembering that this same balance of literal and symbolic language runs throughout Scripture without causing confusion for careful readers. The Psalms describe God’s wings sheltering his people (Psalm 91:4) without teaching God is literally a bird; Jesus describes himself as a door (John 10:9) without claiming to be made of wood. Recognizing symbolic language in one place does not undermine confidence in the plain, historical claims Scripture makes elsewhere, including its plain historical claims about Christ’s bodily resurrection, which this entire hope depends on (1 Corinthians 15:14-17).
Holding the Mystery With Confidence
You do not need to resolve every detail of the New Jerusalem’s architecture to trust the promise behind it. Whether the measurements are exact or symbolic, the reality they point to is guaranteed by the same God who has kept every other promise recorded in Scripture. Paul’s words apply well here: “Now we see only a reflection as in a mirror; then we shall see face to face” (1 Corinthians 13:12). What remains partly mysterious now will be entirely, gloriously clear then.
