Matthew 5:
The old heavens and old earth will be burned, 2 Peter 3:
The new heaven and new earth are the literal replacement of the old heaven and earth, Revelation 21:
i.e., the new physical earth.5 Blessed are the meek, for they will inherit the earth
The old heavens and old earth will be burned, 2 Peter 3:
According to modern physics, our physical bodies and even the atoms in our bodies are perishable. However, our resurrected bodies are not perishable, 1 Corinthians 15:10 But the day of the Lord will come like a thief, and then the heavens will pass away with a roar, and the heavenly bodies will be burned up and dissolved, and the earth and the works that are done on it will be exposed.
The new earth will obey new laws of imperishable physics.50 I declare to you, brothers and sisters, that flesh and blood cannot inherit the kingdom of God, nor does the perishable inherit the imperishable.
The new heaven and new earth are the literal replacement of the old heaven and earth, Revelation 21:
The sun and moon are no longer needed, Revelation 21:1 I saw a new heaven and a new earth, for the first heaven and earth had passed away, and the sea was no more.
We still drink, Luke 22:22 And I saw no temple in the city, for its temple is the Lord God the Almighty and the Lamb. 23And the city has no need of sun or moon to shine on it, for the glory of God gives it light, and its lamp is the Lamb.
Often, Christians ambiguously refer to the new earth or the new physical kingdom of God as "heaven".18 For I tell you I will not drink again from the fruit of the vine until the kingdom of God comes.
