Revelation 21 offers a heart-felt vision of the new heaven and new earth, with a focus on the new Jerusalem, a magnificent city that descends from heaven.
Simplified:

New Heaven and New Earth: The old has passed away, making way for a new creation where God will dwell among His people (verses 1-2).

God’s Dwelling with Humanity: God will wipe away every tear, and there will be no more death, mourning, crying, or pain. The former things have passed away (verses 3-4).

Promise of Renewal: God declares, “I am making everything new!” This signals the fulfillment of His promises and the renewal of all creation (verse 5).

The Holy City, New Jerusalem: Described as coming down from heaven, adorned like a bride. It is a place of great beauty and divine presence (verses 9-14).

Radiant Beauty: The city is described with precious stones, gold, and gates of pearl, symbolizing purity, glory, and divine craftsmanship (verses 18-21).

God’s Eternal Light: The city has no need for the sun or moon because the glory of God gives it light, and the Lamb is its lamp (verses 22-27).

“The Lord bless you and keep you;
The Lord make his face shine on you and be gracious to you;
The Lord turn his face toward you and give you peace.”
Numbers 6:24-26 NIV
