Even as they did not like to retain God in their knowledge, God gave them over to a debased mind, to do those things which are not fitting;...who, knowing the righteous judgment of God, that those who practice such things are deserving of death, not only do the same but also approve of those who practice them.--Romans 1:28, 32
Satan personates the serpent in Eden, regarding this creature as best adapted for his line of temptations. Satan has been increasing in skillful methods by constantly practicing upon the human mind. It is his one purpose to complete the work which he began in Eden, and work the ruin of mankind. Through his mysterious workings he can insinuate himself into the circles of the most educated and refined, for he was once an exalted being, in a high position of responsibility among the heavenly hosts. It is a mistake to represent him as a monstrous being with hoofs and horns, for he is still a fallen angel. He is capable of uniting the highest intellectual greatness with the basest cruelty and the most degrading corruption. If he had not this power, many would escape his snares who are now charmed with his attractive representations and taken captive by his delusions.
As the Spirit of God shall be withdrawn from the earth, Satan's power will be more and more manifest. The knowledge that he had through being in connection with God, as a covering cherub, he will now use to subordinate his subjects who fell from their high estate. He will use every power of his exalted intellect to misrepresent God and to instigate rebellion against Jesus Christ, the Commander of heaven. In the synagogue of Satan he brings under his scepter, and into his counsels, those agents whom he can use to promote his worship. It is not a strange matter to find a species of refinement, and a manifestation of intellectual greatness, in the lives and characters of those who are inspired by fallen angels. Satan can impart scientific knowledge, and give men chapters upon philosophy. He is conversant with history, and versed in worldly wisdom. (The Signs of the Times, May 28, 1894)
REFLECTION: Satan is watching that he may find the mind in an unguarded moment and so get possession of it. We do not want to be ignorant of his devices, neither do we want to be overpowered by his devices. He is pleased with the pictures that represent him as having horns and hoofs, for he has intelligence; he was once an angel of light. To these that trust in their intelligence he will make believe that they can correct the Scriptures....
You need the Holy Spirit of God, the divine power to cooperate with you to discern the trap that the devil is preparing, and escape it. He is going to lead the religious world captive. (Manuscript 11, March 28, 1893)
