5438 Power of Satan.... Deepest darkness.... Eternal light....
July 14, 1952: Book 60
Satan's bondage extends over the whole earth and therefore darkness is spread over the whole earth, for he is the prince of darkness and his uninterrupted activity is aimed at extinguishing the light which flashes here and there on earth and threatens to chase away the darkness. Light is his greatest enemy, because he can only stay where there is darkness, where he can work and unfold all his power and cunning. His kingdom is this earth, his kingdom is the world, which harbours the immature spiritual that is to be set free from his bondage. In this kingdom he has unlimited power as long as the light is denied access, for without light the spiritual will not find the path which leads out of bondage. That is why he will try to hinder the spreading of light, which is to be understood as follows: he undermines the truth wherever he can, for truth is light that has its origin in God. He therefore stands as the prince of darkness in the battle against God, Who is the Eternal Light. Where the light can shine once, his rule has come to an end, and therefore light has to be constantly brought into the darkness, the truth has to be brought to those beings who live in error, in complete ignorance and therefore also have to suffer under Satan's power as long as they are in darkness. The truth can indeed prevail, but only if people voluntarily profess God, the Eternal Light, and therefore become bearers of the light from God themselves. Then Satan has lost all power.... However, he will not give up his position of power so easily and he will fight against the light until the end.... He will take action against the truth everywhere and also find great support from people who are still spiritually dark and willingly allow themselves to be led by him. And since these people are in the majority, it is not easy to take action against error and lies. The darkness is too deep and the light still too weak to chase away the darkness on earth completely. It is the majority of people who are its followers.... Consider this, you humans, that he still has power on the whole earth because men themselves do not strive towards the light but feel well in darkness, then you will also understand that he makes good use of his position, that he lets the cover become thicker and thicker because people themselves support him, because they defend themselves against the radiation of light, which is therefore his endeavour to oppose truth with thickest lies and error so that God cannot be recognised and He loses His followers. It will remain a battle between light and darkness; the number of those who demand light and therefore also receive light will always be small, while the masses prefer darkness and can be offered the untruth no matter how blatantly without resisting it. For Satan has the masses behind him, whereas it is only a small flock which strives towards the light and whose goal is God Himself, the Eternal Light. Yet, one day the light shall break through with victorious power.... Then the deepest darkness will be unable to withstand, then the Eternal Light Itself will appear with such radiant power that everything will perish which opposes it.... Then untruth shall be uncovered and everything that does not strive for eternal truth will be exposed to destruction, but Satan shall lose his power, he will be bound so that he cannot poison the pure atmosphere which has now arisen through God's will.... so that he cannot diminish the light which now shines for humanity on the new earth, which will feel happy in the light of truth and need not fear the darkness for a long time....
Amen
