I think the following paragraph from G. K. Beale’s commentary on the book of Revelation is relevant to all those whom he calls “genuine saints” and thus worthy of being posted on my blog.
In this respect [seeing the eternal perspective of their new home], the churches are to read and reread the book [Revelation] in their assembly so that they may continually be reminded of God’s real, new world, which stands in opposition to the old , fallen system in which they presently live. Such a continual reminder will cause them to realize that their home is not in this old world but in the new world portrayed parabolically [that is as parables] in the heavenly visions. Continued reading of the book will encourage genuine saints to realize that what they believe is not strange and odd, but truly normal from God’s perspective. They will not be discouraged by outside worldliness, including what has crept into the churches, which is always making godly standards appear odd and sinful values seem normal. John refers to true unbelievers in the book as “earth-dwellers” because their ultimate home is on this transient earth, They cannot trust in anything except what their eyes see and their physical senses perceive; they are permanently earthbound, trusting only in earthly security, and will perish with this old order at the end of time when the corrupted cosmos finally is judged and passes away. On the other hand, Christians are like pilgrims passing through this world. As such they are to commit themselves to the revelation of God in the new order so as progressively to reflect and imitate his image and increasingly live according to the values of the new world, not being conformed to the fallen system, its idolatrous images, and associated values (cf. Rom. 12:2).
