In Genesis we find the symbolic prophecy of the defeat of the evil powers as follows:

"I will put enmity between you and the woman,
and between your offspring and hers;
They will strike at your head,
while you strike at their heel."
(Gn 3:15)

The full understanding of this prophecy can only be realized in retrospect. The struggle will be between the "seed of the devil". The devil's progeny are are those angels who joined Lucifer in their revolt against God and all human being who in history have sided or will join the evil powers. The "seed of the woman" can only be Christ and all those who through faith joined Christ in the struggle against the evil powers. The woman herself is Mary, the Mother of God, who gave birth the God's Son. The woman and Christ will stroke at the head of Satan by driving Satan's presence from the hearts of Christians. On the other hand, Satan will strike back by influencing the Judas and the Sanhedrin to put Christ to death. "When Jesus died on the Cross it seemed as though the powers of darkness were victorious over him." Christ "Removed it [Satan] from our midst, nailing it to the cross; despoiling the principalities and the powers, he made a public spectacle of them, leading them away in triumph by it." (Col 2:14-15) By his resurrection he has destroyed the last enemy which is death.

But, how does Christ defeat demonic powers in history?

Before his Assumption Christ said to his Apostles, "All power in heaven and on earth has been given to me. Go, therefore, and make disciples of all nations, baptizing them in the name of the Father, and of the Son, and of the holy Spirit, teaching them to observe all that I have commanded you. And behold, I am with you always, until the end of the age.” (Mt. 28:18-20) Every child born into the world is without grace or under the dominion of Satan. Baptism restores our friendship with God. The Father, Son and Holy Spirit begin to dwell in the heart of the child with a promise of heaven. This gradual defeat of demonic powers will continue till the end of the world because each human being has to decide on which side he stands, on the side of Christ and his Church or on the side of the Satanic Powers.

There is much discussion concerning the end of the world and the so called "Second Coming of Christ" but we simply do not know and Christ did not want us to know as he said: “But of that day and hour no one knows, neither the angels of heaven, nor the Son, but the Father alone." (Mt 24:36) If as the Son of God by nature did not know what the Father had determined, he is not God. He certainly knew the "day and hour" of his final coming but chose to hide it, that is, not making it a part of his human knowledge. As the incarnation hid his divine nature, so too in becoming man this divine knowledge of the "day and hour" of his Second Coming remained hidden to his human nature.

Actually the second coming of Christ began with his Ascension to the Father and that my death I will meet Christ who will judge me individually, so be watchful and be prepared for you do not know the day or hour of your death.

The coming of Christ in glory will be preceded by the resurrection of the dead. "The sea gave up its dead; then Death and Hades gave up their dead. All the dead were judged according to their deeds." (Rv 20:13) Some early Christians wanted to know what kind of body they would have. St. Paul compares a seed of wheat which is placed in the ground and dies but emerges a new living body, the plant. Likewise, "God gives it a body as he chooses, and to each of the seeds its own body." (Rv 15:38)

The evil powers will no longer be free to roam the God's recreation but "The Devil who had led them [humans] astray was thrown into the pool of fire and sulfur, .... There they will be tormented day and night forever and ever." (Rv. 20:10) The same fate awaits the, "Cowards, the unfaithful, the depraved, murderers, the unchaste, sorcerers, idol-worshipers, and deceivers of every sort, their lot is in the burning pool of fire and sulfur, which is the second death.” (Rv 21:8)

 

"Then comes the end,
when he [Christ] hands over the kingdom to his God and Father,
when he has destroyed every sovereignty and every authority and power.
For he must reign until he has put all his enemies under his feet.
The last enemy to be destroyed is death."
(ICor 15:24-26)
