The closing chapters of the book of Revelation describe the final events of this worlds history and the plan of redemption. One of the events it records is the 1,000 years that is commonly known as the Millennium. The word millennium comes from two Latin words joined together — mil, meaning one thousand, and annum, meaning year.
Unfortunately, there is much confusion in the Christian church regarding this doctrine of the Millennium. The only way we can clearly understand the true meaning and purpose of this doctrine is to examine it in the light or context of the Day of Atonement, when the whole universe will be made “at-one-ment” with God.
The purpose of the Millennium is part and parcel of the objectives of the Day of Atonement, which is to eradicate sin and usher in everlasting righteousness. God cannot bring sin to an end, He cannot usher in everlasting righteousness, until all doubt about Him and His dealing with the sin problem is removed.
It is only when the entire universe, including the devil and his angels, as well as the lost, admits to God that “just and true are your ways.” Finally, at the end of the Millennium, when Satan, his angels, and the wicked are judged, they too will confess to God, “just and true are your ways.”
Then, and then only, will God destroy Satan, the originator of sin, the wicked angels who have joined him in the rebellion, and the unbelievers (those who have deliberately, persistently, and ultimately rejected the gift of salvation in Christ.
In this study we will turn our attention to the thousand years, the doctrine of the Millennium, when God will remove all doubt from the minds of the saints about Himself and His dealings with the sin problem.
