Heaven as described in Revelation chapter 21 has many surprises. We could perhaps ask the question, if all of earth and heaven pass away, what really is the point to life? Revelation chapter 21 shows us 4 great things we take with us to heaven and some of them are pretty surprising, in particular the 12 names of the tribes of Israel on the gates of heaven.
