Satan is preparing his deceptions that in his last campaign against the people of God, they may not understand that it is he. 2 Corinthians 11:14: “And no marvel; for Satan himself is transformed into an angel of light.” While some deceived souls are advocating that he does not exist, he is taking them captive, and is working through them to a great extent. Satan knows better than God's people the power that they can have over him, when their strength is in Christ. MYP 51.2
When they humbly entreat the mighty Conqueror for help, the weakest believers in the truth, relying firmly upon Christ, can successfully repulse Satan and all his host. He is too cunning to come openly, boldly, with his temptations, for then the drowsy energies of the Christian would arouse, and he would rely upon the strong and mighty Deliverer. But Satan comes in unperceived, and in disguise he works through the children of disobedience, who profess godliness. Satan will go to the extent of his power to harass, tempt, and mislead God's people. MYP 51.3
He who dared to face, and tempt, and taunt our Lord, and who had power to take Him in his arms and carry Him to a pinnacle of the temple, and up into an exceeding high mountain, will exercise his power to a wonderful degree upon the present generation, who are far inferior in wisdom to their Lord, and who are almost wholly ignorant of Satan's subtlety and strength. MYP 52.1
In a marvelous manner will he affect the bodies of those who are naturally inclined to do his bidding. Satan exults for his own sake that he is regarded as a fiction. When he is made light of, and is represented by some childish illustration, or as some animal, it suits him well. He is thought so inferior that minds are wholly unprepared for his wisely laid plans, and he almost always succeeds well. If his power and subtlety were understood, minds would be prepared to successfully resist him.... MYP 52.2
