This follows from something stated in the previous point: no angels could have continued to exist without being redeemed by the Lord. The following reasons supplement those already given.
The first reason: At the time of the Lord’s First Coming the hells had risen so high that they filled the entire world of spirits that is midway between heaven and hell. They not only wrecked the heaven called the lowest heaven, they also attacked the middle heaven and harassed it in a thousand ways. If the Lord had not preserved it, it would have been destroyed.
This kind of attack by the hells is meant by the tower built in the land of Shinar whose top reached all the way to heaven. The confusion of their languages thwarted those people’s efforts; they were scattered and the city was called Babel (Genesis 11:1–9). The meaning of the tower and of the confusion of their languages is explained in Secrets of Heaven, published in London.
The reason why the hells had risen so high was that by the time the Lord came into the world the whole planet had completely alienated itself from God by worshiping idols and practicing sorcery; and the church that had existed among the children of Israel and later among the Jews had been utterly destroyed by their falsifying and contaminating the Word. After death both of the above groups arrived in the world of spirits. Over time they grew in numbers there to such an extent that they could not have been driven out thereafter if God himself had not come down and used the power of his divine arm to deal with them. The Lord in fact did so, as I have described in Last Judgment, a little work published in London in 1758. While the Lord was in the world, he accomplished their overthrow.
The Lord is again doing something similar today since, as I said, today is his Second Coming, an event foretold throughout the Book of Revelation and in Matthew 24:3, 30; Mark 13:26; Luke 21:27; and Acts 1:11, as well as other places.
A difference is that during his First Coming the hells were swollen with idol-worshipers, sorcerers, and falsifiers of the Word. During this Second Coming the hells are swollen with so-called Christians—some who are steeped in materialist philosophy, and others who have falsified the Word by using it to sanction their made-up faith about three divine persons from eternity and about the Lord’s suffering as the true redemption. The dragon and his two beasts in Revelation 12 and 13 mean the so-called Christians just mentioned.
The second reason why the Lord’s redemption affected angels as well is that the Lord restrains not only all people but also all angels from evil, and keeps them focused instead on what is good. No angels or people are good on their own. Everything good comes from the Lord. When the angels’ footstool (meaning the world of spirits) was stolen, it was as if the platform under someone’s chair was suddenly removed.
The angels are not pure before God. This is something the Prophets and also Job make clear. This is also clear from the fact that there is no such thing as an angel who was not previously a human being. These points support what was said at the beginning of this work under the headings “the faith of the new heaven and the new church in a universal form” and “in a specific form”:
The Lord came into the world to separate hell from the human race. He accomplished this by repeatedly doing battle with hell and conquering it. In this way he gained control over it and forced it to obey him. (Section 2)
Also these words there:
Jehovah God came down and took on a human manifestation for the purpose of forcing everything in heaven and everything in the church back into the divine design. For at that time the power of the Devil, that is, hell, was stronger than the power of heaven, and on earth the power of evil was stronger than the power of goodness; therefore a total damnation stood at the door and threatened. By means of his human manifestation Jehovah God lifted this pending damnation and redeemed both people and angels. From all this it is clear that if the Lord had not come, no one could have been saved. The situation today is similar. If the Lord does not come into the world again, no one can be saved. (Section 3)
