Since the blood redemption of the Cross is the central truth and value of the true faith, it being the "power of God unto salvation" (Rom. 1:16; I Cor. 1:23, 24), any counterfeit system of doctrine which would omit this essential, must force some secondary truth into the place of prominence. Any of the great Scriptural subjects which are of universal interest to humanity, such as physical health, immortality, morality, or religious forms, may be substituted in the false systems, for that which is vital. And while those subjects are all found in their proper relations and importance in the true faith, the fact that people are universally inclined to give attention to them furnishes an opportunity for Satan to make a strong appeal to humanity through them; using these subjects as central truths in his false and counterfeit systems. Many are easily led to fix their attention upon the secondary things, and to neglect wholly the one primary thing; especially is this true since the secondary things are tangible and seen: while the one essential thing is spiritual and unseen; and Satan has blinded their eyes toward that which is of eternal value. A system of doctrine may, then, be formed which includes every truth of Scripture save one; exalting the _Person_ of Christ, but not His atoning _work_, and emphasizing some secondary truth as its central value. This system will be readily accepted by blinded humanity, though the real power of God unto salvation has been carefully withdrawn. Naturally it would be supposed that such Satan-inspired systems would have no value or power, since there could be no Divine favor upon them. Such a supposition would be possible only because of the prevailing misunderstanding as to the real power of Satan. If the description given of him in Scripture is accepted, he will be seen to be possessed with miraculous power; able to perform such marvels that the whole world is led to wonder and then to worship. He is free also to bestow this miraculous power upon others (Rev. 13:2). So it is no marvel if his ministers, who appear as the ministers of righteousness, are able to exert superhuman power when it is directly in the interest of the Satanic projects. The great power of Satan has doubtless been active along these lines during all the ages past; for it is impossible that humanity should have worshipped other gods blindly without some recompense, and it is Satan himself who has been thus worshipped (Lev. 17:7; II Chron. 11:15; Rev. 9:20).
