What the CT'ers do is simply sign some sort of allegorical or figurative meaning to 1,000 years and force it to me a long period of time.
Are you sure that is what they do? Covenant theology is Reformed theology. Calvinism can be Covenant or Dispensational. If I am not mistaken, you consider yourself Calvinist or Calvinistic. So, for you to make such a claim is remarkable as sure you know how careful the Reformers were to get it right according to Scripture.
The book of Revelation is written with allegorical and figurative symbols. It makes perfect sense to interpret it just as it is written instead as though it were historical narrative.
The millennium (a thousand years) is logically a representative number for a number of reasons. Not the least of which is that no one is able to know the time of Christ's return except God himself, according to the scriptures. One thousand as a literal number is countable---not unlike dispensationalist counting all the numbers in Daniel to try and second guess God's decree and find out when the Christ will return.
So where does CT look to find what 1000 is representing? Within the Bible itself for it uses numbers symbolically but in a literal way throughout. Sevens, threes, tens, twelves and multiples of these numbers.
In Scripture the number 10 represents divine completion and God's almighty power and government.
It is often used as a marker of time (waiting, duration, completion, or testing)
Dan 1:12-15--ten-day test
Rev 2:10 ten days of tribulation
Gen 25:55 Delay before departure etc. etc
Generations as a time span" Adam to Noah, Shem to Abram.
Ten times (repeated duration) Gen 31:7; Numbers 14:22
The broader biblical use of ten is a number of completion and accountability, especially in covenantal contexts.
Ten as a time measurement carries a theological significance rather than merely a mathematical significance. And in case you think this is unreasonable and unfounded, consider God himself. There is not one idle word or number in the historical account of redemption. It comes from a God who has no idleness or arbitrariness in anything. Everything counts for more than we can see on the surface. His use of numbers is never without theological significance. The number 10 functions as a symbol for completeness in testing, probation, and covenantal accountability---a full period determined by God, after which judgement or vindication follows.
It marks covenantal accountability. Ten is tied to law and covenant (ten commandments). When used in time, it indicates a moral evaluation period.
Why 1,000 is read symbolically.
Revelation is apocalyptic genre where numbers are symbolic.
- 7= divine completeness
- 10= completeness/fullness
- 12=covenant peoples
- 1,000=10x10x10 fullness raised to it highest intensity
Biblical precedent for symbolic "long time"
- Psalm 50:10 – “the cattle on a thousand hills”
- Psalm 90:4 – “a thousand years…as yesterday”
- 2 Peter 3:8 – “with the Lord one day is as a thousand years”
The millennium is the period between the two advents.
Jesus teaches of to ages. This age (after first advent) and the age to come (arrives at his second coming). Matt 12:32; Mark 10:29-30; Luke 18:30.
Marriage belongs to this age. Resurrection life belongs to next age (Luke 20:34-36).
Harvest at the end of this age (Matt13:39-40,49).
The apostles teach two ages. (Eph 1:21; Gal 1:4; 1 Cor 4:4)
No intermediate age between resurrection and consummation is mentioned.
