I explained why the Day of the Lord is unlikely to begin at the start of the tribulation and analyzed what it means for the Day of the Lord to come as a “thief in the night” in separate articles. In this article, I examine the teaching that the Day of the Lord will last for 1,000 years in this article.
Some teach that the Day of the Lord will last precisely 1,000 years. Some proponents of this view believe the Day of the Lord will coincide with the Millennium while others believe it will start at the end of the Millennium. Those who teach that the Day of the Lord will last for 1,000 years cite Psalm 90 and 2 Peter 3:3-13. Here are the key parts from each chapter contributing to this viewpoint:
“(1) Lord, thou hast been our dwelling place in all generations. (2) Before the mountains were brought forth, or ever thou hadst formed the earth and the world, even from everlasting to everlasting, thou art God. (3) Thou turnest man to destruction; and sayest, Return, ye children of men. (4) For a thousand years in thy sight are but as yesterday when it is past, and as a watch in the night.” (Psalm 90:1-4)”
“(8) But, beloved, be not ignorant of this one thing, that one day is with the Lord as a thousand years, and a thousand years as one day. (9) The Lord is not slack concerning his promise, as some men count slackness; but is longsuffering to us-ward, not willing that any should perish, but that all should come to repentance. (10) But the day of the Lord will come as a thief in the night; in the which the heavens shall pass away with a great noise, and the elements shall melt with fervent heat, the earth also and the works that are therein shall be burned up. (11) Seeing then that all these things shall be dissolved, what manner of persons ought ye to be in all holy conversation and godliness, (12) Looking for and hasting unto the coming of the day of God, wherein the heavens being on fire shall be dissolved, and the elements shall melt with fervent heat? (13) Nevertheless we, according to his promise, look for new heavens and a new earth, wherein dwelleth righteousness.” (2 Peter 3:8-13)
If you read these passages closely, you’ll notice that each passage is comparing a day with the Lord to a thousand years. The recognition that a comparison is being made is critical because it means that a direct statement that “a day for the Lord is a thousand years” is not being made. The writer of Psalm 90 and Peter used the comparison to convey the notion that the Lord’s timing is entirely different from our sense of timing. The Lord is eternal while our lives are relatively short, so a long time to us is not a long time to Him.
Therefore, I would caution you to accept the notion that the Day of the Lord will last for precisely 1,000 years.
