Verse-by-Verse Explanation of Revelation Chapter 21 (KJV)
Verses 1–2: A New Heaven and a New Earth
“And I saw a new heaven and a new earth: for the first heaven and the first earth were passed away; and there was no more sea.”
“And I John saw the holy city, new Jerusalem, coming down from God out of heaven, prepared as a bride adorned for her husband.”
John sees the final stage of God’s redemptive plan—a completely new creation. The old, corrupted world is gone, and there is no more sea, which in biblical times represented chaos and separation. The New Jerusalem, a radiant city, comes down from heaven, prepared like a bride for her husband.
Key Insight: God is not patching the old world; He is creating something entirely new and perfect.
Verses 3–4: God Will Dwell With His People
“And I heard a great voice out of heaven saying, Behold, the tabernacle of God is with men…”
God declares that He will now live among His people—not in a tabernacle, temple, or vision, but in person. He will wipe away every tear, and death, sorrow, and pain will be no more.
Key Insight: This is the complete restoration of God’s presence with humanity, reversing the curse of sin and death.
Verse 5: Behold, I Make All Things New
“And he that sat upon the throne said, Behold, I make all things new…”
God, seated on the throne, personally confirms this transformation. He instructs John to write down His words because they are faithful and true.
Key Insight: These are not symbolic promises. God’s authority ensures their certainty.
Verses 6–7: The Gift of Eternal Life
“I will give unto him that is athirst of the fountain of the water of life freely.”
God invites anyone who thirsts spiritually to drink freely from the fountain of life. Those who overcome through faith in Christ will inherit all things and be called sons and daughters of God.
Key Insight: Salvation is a free gift, offered without cost to all who believe and endure.
Verse 8: The Destiny of the Wicked
“But the fearful, and unbelieving… shall have their part in the lake which burneth with fire and brimstone…”
God contrasts the destiny of the faithful with the fate of the wicked. Those who reject God, including the unbelieving and immoral, will face eternal separation in the lake of fire—this is the second death.
Key Insight: God is not only loving but also just. Eternal life is available, but rebellion carries consequences.
The Vision of the New Jerusalem (Verses 9–21)
Verses 9–11: The Glory of the Holy City
“Come hither, I will shew thee the bride, the Lamb’s wife…”
An angel shows John the New Jerusalem, described as the Lamb’s bride—radiant, pure, and prepared. The city is illuminated with the glory of God, resembling a precious jasper stone.
Key Insight: The Church, perfected and holy, is now fully united with Christ.
Verses 12–14: Gates and Foundations
“It had a wall great and high, and had twelve gates…”
The city has 12 gates named after the 12 tribes of Israel and 12 foundations named after the apostles. This symbolizes the unity of the Old and New Testaments.
Key Insight: God’s covenant with Israel and the Church are both honored and fulfilled in this eternal city.
Verses 15–17: The Dimensions of the City
“And he measured the city…”
The city is a perfect square—12,000 furlongs (about 1,400 miles) in length, width, and height. The wall is 144 cubits high. These numbers signify completeness and divine perfection.
Key Insight: The precise symmetry shows that everything in God’s kingdom is measured, intentional, and perfect.
Verses 18–21: Materials of Beauty
“The city was pure gold, like unto clear glass…”
The city is built with dazzling materials—clear gold, jasper walls, and twelve different precious stones decorating its foundations. Each gate is made from a single pearl, and streets are paved with transparent gold.
Key Insight: The unmatched beauty of the city reflects the holiness and glory of God.
Life Inside the New Jerusalem (Verses 22–27)
Verse 22: No Temple in the City
“And I saw no temple therein: for the Lord God Almighty and the Lamb are the temple of it.”
There is no physical temple in the city because God’s presence fills it completely. Worship is direct, not mediated through buildings or rituals.
Key Insight: Relationship with God is now face-to-face, unmediated and eternal.
Verse 23: Light from the Lamb
“The city had no need of the sun, neither of the moon…”
The city doesn’t rely on natural light. The glory of God and Jesus Christ serve as its eternal light source.

“There shall in no wise enter into it any thing that defileth…”
Nothing impure will ever enter this city. Only those written in the Lamb’s Book of Life will be allowed in.
