While Revelation 20 makes a statement about a one thousand year reign, it should not be taken literally. To begin with, there is no Scriptural precedent to take it literally – in fact quite to the contrary. There is no other place in Scripture where “a thousand years” (or anything like it) is used literally2,3,4,5,6,7,8,9,10,11,12. We see “thousand” used figuratively in books of history2,7, poetry3,4,8,10,13, New Testament epistle12, other books of prophecy6,9 and other places in Revelation itself5.
We are reading it within the broader prophetic and highly figurative vision of John. Furthermore, to take “one thousand years” literally in Revelation 20 would be out of context for rest of Scripture, being quite literally (no pun intended), the only instance.
By the time we get to the passage of Scripture that promoters of this “literal thousand year reign” doctrine stake their claim on1, Scripture has well established a figurative use for “a thousand years”2,3,4,5,6,7,8,9,10,11,12,13 (and not at all unlike many secular examples). Indeed, without the clouding lens of a presupposed doctrine that requires a certain interpretation, the Revelation 20 text is simply communicating to the reader a very long (everlasting2,3,4,7,11,12) and triumphal (complete2,3,5,6,7,8,9,10,11,12,13) reign of Christ and the Saints.
