After God has defeated all of His foes and judged the world, He will establish a new heaven and a new earth.

Revelations 21:1-8
And I saw a new heaven and a new earth; for the first heaven and the first earth passed away, and there is no longer any sea. And I saw the holy city, a new Jerusalem, coming down out of heaven from God, made ready as a bride adorned for her husband. And I heard a loud voice from the throne, saying, "Behold, the tabernacle of God is among men, and He shall dwell among them, and they shall be His people, and God Himself shall be among them, And He shall wipe away every tear from their eyes; and there shall no longer be any death; there shall no longer be any mourning, or crying, or pain; the first things have passed away." And He who sits on the throne said, "Behold, I am making all things new." And He said, "Write, for these words are faithful and true." And He said to me, "It is done. I am the Alpha and the Omega, the beginning and the end. I will give to the one who thirsts from the spring of the water of life without cost. He who overcomes shall inherit these things, and I will be his God and he will be My son. But for the cowardly and unbelieving and abominable and murderers and imoral persons and sorcerers and idolaters and all liars, their part will be in the lake that burns with fire and brimstone, which is the second death."
