Revelation 22:3-5

There will no longer exist anything that is cursed [because sin and illness and death are gone]; and the throne of God and of the Lamb will be in it, and His bond-servants will serve and worship Him [with great awe and joy and loving devotion]; [Zech 14:21] they will [be privileged to] see His face, and His name will be on their foreheads. [Ps 17:15; Matt 5:48; 1 John 3:2] And there will no longer be night; they have no need for lamplight or sunlight, because the Lord God will illumine them; and they will reign [as kings] forever and ever. [Zech 14:7; Rev 1:6]
