Q. In your email today regarding ‘revival’, part of your answer was that when the Lord returns to earth there will only be believers…if there is sin in the Millennium, how can all be believers? Have I missed something or got something wrong?
A. In the Sheep and Goat judgment, which takes place just after the 2nd Coming, the Lord will separate all the living survivors of the Great Tribulation into believers (sheep) and unbelievers (goats). He’ll welcome the believers in to the Millennial Kingdom (Matt. 25:34) and will send the unbelievers to “the place prepared for the devil and his angels” (Matt. 25:41). Therefore at the beginning of the Millennium there will be no unbelievers on Earth.
Still being in their natural states, the Tribulation believers who enter the Millennium will be capable of sin, as will the children they will bear during the Millennium.
