The kingdom of God isn’t something any human can understand until we get there. There is this passage in Revelation that describes it probably the best.
And there shall no longer be any curse; and the throne of God and of the Lamb shall be in it, and His bond-servants shall serve Him; and they shall see His face, and His name shall be on their foreheads. And there shall no longer be any night; and they shall not have need of the light of a lamp nor the light of the sun, because the Lord God shall illumine them; and they shall reign forever and ever.
Basically, the kingdom of God is the perfect place.
