Where in Revelation are the new heavens and new earth described?

Les explains that when Isaiah speaks of the new heavens and new earth, a Bible student's mind should immediately jump to Revelation 21 and 22. He notes that even though the present creation is going to be destroyed, God will create new heavens and a new earth for all eternity, and Isaiah refers to the same event. Les also emphasizes that Israel will never pass off the scene; even after the millennial reign and the total destruction of the universe, Israel remains the apple of God's eye in the eternal state. He adds that members of the body of Christ are in an even better position than Israel, though the world tries to put Israel out of the picture, God will never lose sight of His covenant people.
