The Bible is like a gigantic cycle: it begins with a beautiful place of safety and security (Gen. 1; 2); sin, doubt, and disobedience come in (Gen. 3); then we follow the story of sin and disobedience from the beginning (Gen. 3); to the end (Rev. 20). The New Jerusalem narrative attempts to describe the peace, security, and safety that will be in place after the destruction of sin (Rev. 21). Scripture would not present a complete picture without the book of Revelation, nor would Revelation be complete without these last two important chapters.
Is the New Jerusalem a literal city like those today? Or is it a symbol of an indescribable reality? If it is like ancient Jewish pictures of the glorious future, it is more symbolic than literal. God did not intend it to satisfy the reader's curiosity about the architecture of the future, but to teach spiritual lessons that will change lives today.
Tobit (in the Apocrypha), for example, describes an end-time Jerusalem whose gates consist of sapphire and emerald, and whose walls and streets are embedded with precious stones (Tobit 13:21, 22, Douay; 13:17, LXX). But this description is just one of the many things for which Tobit praises God (Tobit 13:1, Douay). Isaiah predicts foundations of sapphire, jeweled gates, and walls of precious stones (Isa. 54:11, 12), but they too are there for praise (Isa. 60:10-18, especially verse 18). Zechariah, on the other hand, predicts that Jerusalem will be without walls, because the Lord will be a wall of fire around it (Zech. 2:4, 5). So to assume that all of this description is meant as literal is questionable.
What relevance does the vision have for us in a skeptical age? The images are those of the author's time and place, but the central theme is clear. Everything that human beings have hoped and dreamed for is attained, not by human effort, but in relationship with the Lamb. And that relationship begins now. The vision of the future New Jerusalem keeps our minds and hearts focused on the one thing that really matters.
Lord, help me to remember every day that paradise is not a Caribbean island, that the ideal city is not Hollywood, but that I will find the ultimate hopes and dreams of my life in relationship with You.
