There can be no thousand years of righteousness and peace on earth while the great Enemy of God and man is at large. Post-millenarians, who expect the Kingdom to be brought in by the preaching of the Gospel and the activities of the Church, and Peace-idealists and Social-reformers who look for a Golden Age to be brought about by legislation and civilization, all leave out of their schemes and considerations one dominating factor, namely, the Devil. Behind all anit-christian systems back of all the inveterate opposition to the Gospel, beneath all the evil and wickedness which stalks rampant through the earth, is that old Serpent, the Devil. And nothing finite can remove him. Nothing human can disturb him. None on earth can bind him. Man is incompetent to cope with his mighty adversary. Legislation cannot reach him, and the Church is powerless to rid the world of his awful presence. The only One who is mightier than he, is God -- the Almighty, and there can be no Golden Age, until the Son of God Himself returns in person and removes and imprisons the Arch-Foe.
The removal of Satan from this earth is described in Rev.20:1-3, "and I saw an angel  come down from heaven, having the key of the Bottomless Pit and a great chain in his hand. And he laid hold on the Dragon, that old Serpent, which is the Devil, and Satan, and bound him a thousand years, and cast him into the Bottomless Pit, and shut him up, and set a seal upon him, that he should deceive the nations no more, till the thousand years shall be fulfilled." Satan will be "bound" which is the fulfillment of our Lord's word in Matt.12:29 -- "How can one enter a "strong man's house, and spoil his goods, except he first bind the strong man? and then he will spoil his house." The "strong man" is our , the Devil' his "house" is the children of this world, in contradistinction to the children of God who are the "House" of Christ (Heb.3:6); the "binding" of the Strong Man is described in the Passage quoted above from Rev.20; the "spoiling of his house" is the delivering of his captives (see Is.42:7). Satan will be "cast into the Bottomless Pit" which is the fulfillment of Is.14 -- "How art thou fallen from heaven, O Lucifer, son of the morning! how art thou cut down to the ground which didst weaken the nations! For thou hast said in thine heart, I will ascend into Heaven, I will exalt my throne above the stars of God: I will sit also upon the mount of the congregation, in the sides of the north: I will ascend above the heights of the clouds; I will be like the Most High. Yet thou shalt be brought down to Hell, to the sides of the Pit" (vss.12-15). Satan will be shut up in the Bottomless Pit and a "seal" shall be set upon him, which is God's answer to that which we read of in Matt.27:66, "So they went and made the sepulcher sure, sealing the stone, and setting a watch -- what he has sown that he also reap. Thus will terminate that struggle which has lasted for six thousand years, a struggle which has been waged for the dominion of the earth.
At last the "roaring lion" (1 Peter 5:8) will have been overcome, overcome by the Lion of the tribe of Judah. The Man with the bruised heel will have crushed the Serpent's head, and the word spoken in Eden will then be fully accomplished. And who can describe or even imagine the blessed consequences! No more shall the brethren be accused before God (Rev.12:10). No more shall the daughters of Abraham be "bound, lo, these eighteen years" (Luke 13:16). No more shall satan tempt and try, harass and hinder the saints of God. For a thousand years the earth shall be rid of the Evil One and in his place there shall come "Times of Refreshing from the presence of the Lord." And this leads us to consider,
 We believe this "angel" to be the Lord Jesus Himself--the uncreated Angel of the Covenant (Mal. 3:1). If it should be asked, Why term Him an angel? the answer is, To connect Him with Israel, the covenant and earthly people. See Gen. 22:15, 16; 48:16; Ex. 3:2; and compare Rev. 7:2, 3; 8:3; 10:1.
