Christianity believes that Jesus will return and restore the Earth to what it was like before sin.
God will essentially bring heaven down to Earth and we will live our lives to his glory without sin. It will be like life now, businesses running, sports, entertainment.....but there will be no more sin or suffering and everyone will love the LORD and do all things to his glory. We will be able to worship God in his very near presence and do as He's created us to do for all eternity.
Interestingly there will no longer be marriages, we will be more like you would imagine angels to be....completely content in our singleness.
Isaiah 65:17–25 (NLT) — 17 “Look! I am creating new heavens and a new earth, and no one will even think about the old ones anymore. 18 Be glad; rejoice forever in my creation! And look! I will create Jerusalem as a place of happiness. Her people will be a source of joy. 19 I will rejoice over Jerusalem and delight in my people. And the sound of weeping and crying will be heard in it no more. 20 “No longer will babies die when only a few days old. No longer will adults die before they have lived a full life. No longer will people be considered old at one hundred! Only the cursed will die that young! 21 In those days people will live in the houses they build and eat the fruit of their own vineyards. 22 Unlike the past, invaders will not take their houses and confiscate their vineyards. For my people will live as long as trees, and my chosen ones will have time to enjoy their hard-won gains. 23 They will not work in vain, and their children will not be doomed to misfortune. For they are people blessed by the LORD, and their children, too, will be blessed. 24 I will answer them before they even call to me. While they are still talking about their needs, I will go ahead and answer their prayers! 25 The wolf and the lamb will feed together. The lion will eat hay like a cow. But the snakes will eat dust. In those days no one will be hurt or destroyed on my holy mountain. I, the LORD, have spoken!”
Revelation 21:2–7 (NLT) — 2 And I saw the holy city, the new Jerusalem, coming down from God out of heaven like a bride beautifully dressed for her husband. 3 I heard a loud shout from the throne, saying, “Look, God’s home is now among his people! He will live with them, and they will be his people. God himself will be with them. 4 He will wipe every tear from their eyes, and there will be no more death or sorrow or crying or pain. All these things are gone forever.” 5 And the one sitting on the throne said, “Look, I am making everything new!” And then he said to me, “Write this down, for what I tell you is trustworthy and true.” 6 And he also said, “It is finished! I am the Alpha and the Omega—the Beginning and the End. To all who are thirsty I will give freely from the springs of the water of life. 7 All who are victorious will inherit all these blessings, and I will be their God, and they will be my children.
