The Cosmic War is an interesting subject. One that has fascinated me for many years. I do think I have learned some reasons of the WHY for the War as well as some of the earliest strategic moves in the planning of the War to achieve the final outcome of the War which of course is for one side to win over another.
Lucifer the highly anointed Cherubim is described in the Bible as a being of light and was created as one of sixteen very unique special class of Angel. His primary purpose was the protection of the throne of God Most High, and Lucifer was the most highly anointed of this special class of being as well as being placed in charge over the other fifteen Cherubim that was the guard of the Throne of the Most High. They were known as the Keepers of the Emerald Throne. The Emerald Throne represents the seat of all authority in the multiverse.
There came a time when Lucifer rebelled against that throne, and took one third of all of the created Angels with him in the rebellion. That one third was numbered at 200,000,000 Angelic beings. All that went with Lucifer were underneath him in both stature and authority so he was the most powerful of the group and he understood this very well. There were 600,000,000 created Angelic beings at the beginning and at that time that was all of the life there was in the whole multiverse.
God fought against the rebels with the 400,000,000 Angels he had left. God using Michael won the battle. God sent 2 Angels to Lucifer named Enoch and Elijah with terms of peace and terms for reinstatement into the family of Angelic beings. Lucifer refused the terms offered and so their judgment was Exile to a solar system very far away from the Emerald Throne dimension. Lucifer was exiled to the Planet Mars along with his followers and there was no more further judgment at that time.
God decided to create human beings on Earth. God knew that Lucifer would be watching. Humans were created to have all authority over the works of Gods hands and so Adam and Eve were created. A ceremony was held at the creation site on Earth and God anointed Adam and Eve as human beings and made them the King and Queen of the Heavens over all the works of Gods hands. God told the new Humans, that they could interact with any Angelic beings on the Earth for many were here for the celebration and the ceremony of the new King and Queen. God told them they were not to interact with the one known as Lucifer.
After the ceremony ended, many Angels left with God but many also stayed on for a time. Lucifer came to Eve glowing like the Cherubim he was and Lucifer found her alone and convinced her to have sexual relations with him, and that God had sent him Lucifer to her for sexual relations so the royal line could be continued through the new Queen Eve. Lucifer hid his true identity from Eve and she fell for the trick, as Lucifer was irresistible to her as no other being there was like him in appearance.
After their sexual intercourse Eve went and found Adam and brought him to Lucifer. Lucifer explained to Adam he was a messenger from God to them and so Adam also had sexual intercourse with Eve and with Lucifer. The first threesome. A cosmic orgy. Eve became pregnant by both Adam and Lucifer, she had twins, Cain and Able.
God showed up later and asked what they had done? Adam told God what happened. God found Lucifer and placed curses on him for his deceptions. God knew this would happen because God knew Lucifer better than Lucifer knew himself. When God created Adam and Eve they were like little children, they did not know right from wrong except for the fact they were not to have anything to do with Lucifer, but Lucifer hid his identity from them.
God was torn by what had happened as the power of love arose in his heart, for he did not want to harm either Lucifer or Adam and Eve as they are his Children. Nevertheless a change would have to be made from the imbalance of Lucifers rebellion on the multiverse and as well as the Adam and Eve problem that exacerbated the imbalance in the creation. In other words, God knew he made a mistake and so to correct the problem, there had to be an answer for the imbalance problem.
In the Bible God repented for making mankind on the Earth. This can be found in Genesis 6:6 where it says,
And it repented the Lord that he had made man on the Earth, and it grieved Him at His heart.
