Discontent and wickedness will not be eradicated from the hearts of men, but will be kept beneath the surface by means of the Iron Rod. These verses do not conflict with those Scriptures which speak of great blessings, spiritual as well as temporal, coming upon the Gentiles during the Millennium, but warn us that the Kingdom age is not the Perfect State, and that while most if not all will worship outwardly, yet at heart many are still the enemies of the Lord. Thus will be fully and finally demonstrated the incurable evil of the human heart. Even a thousand years of millennial blessedness, with Satan away from the earth, will not effect any change in man. Let Satan be loosed and allowed to go forth once more and deceive the nations, and it shall be seen that the carnal mind is still enmity against God, and prefers a Murderer to the Lord Jesus.
Nothing avails short of a new creation.
Miracles, a beneficent environment, temporal blessings - nothing without, can alter fallen and depraved human nature. What follows is told us in few words. Satan himself is cast into the Lake of Fire where the Beast and the False Prophet are, and all of the unsaved dead from Cain onwards will be raised from their graves, to stand before the great white Throne and be judged according to their works. The purpose of this judgment is to determine their respective sentences, for there will be degrees of punishment among the lost, as there will be degrees of glory among the redeemed. If it is not, there is nothing before you but a hopeless and endless eternity of suffering, of suffering so fearful that no human pen or tongue can adequately depict it.
