As believers, we have a hope (confident expectation) in how things are going to end. Or even better, how the end of redemptive history is the beginning of an even better story! The Apostle John is writing to real people gathered as real churches (Rev 2-3). They are about to experience a brutal persecution under the reign of the Roman Emperor, Domitian. Revelation is intended to give Christians hope. So how does he encourage believers who are about to suffer? By providing them with a beautiful promise from God of a new heaven, earth, and city of God. A place where "death shall be no more, neither shall there be mourning, nor crying, nor pain anymore” (Rev 21:4). Everything will be new (21:5a), it is certain (21:6), we will be completely satisfied (21:6b), and we will be God’s sons (21:7).
