New heaven and new earth

In the new heaven and new earth, who lives where?

Your question is referencing Isaiah 65:17; 66:22; 2 Peter 3:13; and Revelation 21:1. The Bible tells us that God is preparing a wonderful, perfect eternity for us, but does not get into specifics like your question is seeking.

The most important part of our eternity is that we will spend it with God. He guarantees that. Jesus said, “And if I go and prepare a place for you, I will come back and take you to be with me that you also may be where I am” (John 14:3).

We will leave the details of our eternity with God in his hands, knowing and trusting that we will be the recipients of his lavish love forever (cf. Revelation 21 and 22).
