581. What does the Bible have to say about God’s new creation?

After the Last Judgement, God will replace the old creation with a new creation: “He [God] will dwell with them, and they shall be His people. God Himself will be with them and be their God” (Revelation 21: 3). Thereby the expectation expressed in 2 Peter 3: 13 will be fulfilled: “Nevertheless we, according to His promise, look for new heavens and a new earth in which righteousness dwells.” This kingdom of God will be eternal, and then God will be all in all (1 Corinthians 15: 28).
