About Satan

​[4] I said: ‘Satan can take it on the chin a thousand times a thousand, yet after a thousand times a thousand blows he steadily remains the same, most wicked enemy of God and of everything good and true emanating from God’s Spirit.(GGJ Book 3, chap. 9)
 
In order to understand and appreciate this deed, you must first know how the devils get into a person and what they are in reality, so that the casting out can become comprehensible to you. To make this clear to you, I must go far back and lead you into earlier eons when there was no material world as yet but only the realm of spirits.
Out of presumption and defiance, the first angel, as the bearer of light into the farthest spaces of the heaven of spirits, abused his might and - together with his adherents - rebelled against Me. And since he and his accomplices had no intention of ever returning, they were banned into matter and compelled to set out on the long road of progressive purification in order to return to their once better state. This process of purification is still on today until all will have again become what they once were, namely, recognizers of My might and love and active promoters of My great plan of creation.
Now behold, in that distant time when the individual liberty of the spirit was established as inviolable, which is still the case today, the spirits, including Satan himself, were free either to return from their wrong direction or not. But since the spirits were not all equal in recognition, goodness and insight - just as still today there are no two beings which are spiritually alike – the ways in which those spirits thought and acted were most varied. One was satisfied with his spiritual level, another was not. One was steadfast in resisting the temptation of the more wicked,
whereas another opposed the influence of the better ones. Hence, there did not exist a proper progression, but there were as many different opinions and ideas about Me, the world and the necessary development as there were spiritually thinking beings.
This great diversity, existing among the good spirits as well as among the evil, who prefer to regard Satan as their deity in the same way as the good regard Me, - this diversity is the basis for the spiritual life and activity necessary for the continuance of the great realm of spirits. Although the great multitude of fallen spirits under their principal leaders took a direction other than the one destined for all, their actions, which are opposed to Me and My principle of good, must nevertheless serve My purpose. In the results, which are not according to their wishes, they must recognise My omnipotence which they cannot evade whatever they do. (Sermons of the Lord, chap. 15)
