To this line of argument there is a very obvious reply. What, it may be asked, of those on whom "the manifestation of the truth" produces no effect? What of those who in spite of all this plain appeal to conscience neither see nor feel anything? It is sadly obvious that this is no mere supposition; the Gospel remains a secret, an impotent ineffective secret, to many who hear it again and again. Paul faces the difficulty without flinching, though the answer is appalling. "If our Gospel _is_ veiled (and the melancholy fact cannot be denied), it is veiled in the case of the perishing." The fact that it remains hidden from some men is their condemnation; it marks them out as persons on the way to destruction. The Apostle proceeds to explain himself further. As far as the rationale can be given of what is finally irrational, he interprets the moral situation for us. The perishing people in question are unbelievers, whose thoughts, or minds, the god of this world has blinded.[39] The intention of this blinding is conveyed in the last words of ver. 4: "that the illumination which proceeds from the Gospel, the Gospel of the glory of Christ, who is the image of God, may not dawn upon them." Let these solemn words appeal to our hearts and consciences, before we attempt to criticise them. Let us have a due impression of the stupendous facts to which they refer, before we raise difficulties about them, or say rashly that the expression is disproportioned to the truth. To St. Paul the Gospel was a very great thing. A light issued from it so dazzling, so overwhelming, in its splendour and illuminative power, that it might well appear incredible that men should not see it. The powers counteracting it, "the world-rulers of this darkness," must surely, to judge by their success, have an immense influence. Even more than an immense influence, they must have an immense malignity. For what a blessedness it meant for men, that that light should dawn upon them! What a deprivation and loss, that its brightness should be obscured! Paul's whole sense of the might and malignity of the powers of darkness is condensed in the title which he here gives to their head--"_the god_ of this world." It is literally "of this age," the period of time which extends to Christ's coming again. The dominion of evil is not unlimited, in duration; but while it lasts it is awful in its intensity and range. It does not seem an extravagance to the Apostle to describe Satan as the god of the present æon; and if it seems extravagant to us, we may remind ourselves that our Saviour also twice speaks of him as "_the prince_ of this world." Who but Christ Himself, or a soul like St. Paul in complete sympathy with the mind and work of Christ, is capable of seeing and feeling the incalculable mass of the forces which are at work in the world to defeat the Gospel? What sleepy conscience, what moral mediocrity, itself purblind, only dimly conscious of the height
