I find only one place in Rev 20 where a/the thousand years equates to TIME. There is NOWHERE in Scripture that proves there will be ONE thousand more years of TIME after Christ comes again. You have nothing but Rev 20 which shows a thousand years equate to time when living saints both lived and reigned and also shall live with Christ. You ignore the tenses to promote your unbiblical doctrine. The martyred souls in heaven lived and reigned in TIME, symbolized a thousand years. Other saints who are not part of the martyred souls in heaven shall also reign with Christ in TIME, symbolized a thousand years.
Revelation 20:4 (KJV) ... they lived and reigned with Christ a thousand years.
Revelation 20:6 (KJV) Blessed and holy is he that hath part in the first resurrection: on such the second death hath no power, but they shall be priests of God and of Christ, and shall reign with him a thousand years.
This past tense living and reigning, and future tense reign with Christ speak of TIME, which is what a thousand years equate. TIME is given this earth, because there is no time in heaven. Heaven is the eternal dwelling place of God. When we read John's vision with common sense, instead of trying to promote an unbiblical doctrine we find John uses a/the thousand years to equate to time for building the spiritual Kingdom of God in heaven as the Gospel is proclaimed throughout the earth. It stands to reason why John is told to write TIME as a/the thousand years and not literal/physical time on this earth, because if John gave the exact amount of time on this earth for Satan's binding, as the Gospel is proclaimed then we could determine what God tells us no man shall know.
