The last two verses in this passage are very striking. We have seen already two agents in the destruction of men's souls. They perish by their own agency, in that they do not welcome and love the truth; and they perish by the malevolence of the devil, who avails himself of this dislike to the truth to befool them by falsehood, and lead them ever further and further astray. But here we have a third agent, most surprising of all, God Himself. "For this cause God sendeth them a working of error, that they should believe a lie: that they all might be judged who believed not the truth, but had pleasure in unrighteousness." Is God, then, the author of falsehood? Do the delusions that possess the minds of men, and lead them to eternal ruin, owe their strength to Him? Can He intend anybody to believe a lie, and especially a lie with such terrific consequences as are here in view? The opening words--"for this cause"--supply the answer to these questions. For this cause, _i.e._, because they have not loved the truth, but in their liking for evil have turned their backs upon it, for this cause God's judgment comes upon them, binding them to their guilt. Nothing is more certain, however we may choose to express it, than the word of the wise man: "His own iniquities shall take the wicked himself, and he shall be holden with the cords of his sin." He chooses his own way, and he gets his fill of it. He loves the deceit of unrighteousness, the falsehood which delivers him from God and from His law; and by God's righteous judgment, acting through the constitution of our nature, he comes continually more and more under its power. He believes the lie, just as a good man believes the truth; he becomes every day more hopelessly beclouded in error; and the end is that he is judged. The judgment is based, not on his intellectual, but on his _moral_ state. It is true he has been deluded, but his delusion is due to this, that he had pleasure in unrighteousness. It was this evil in him which gave weight to the sophistries of Satan.
Again and again in Scripture this is represented as the punishment of the wicked, that God gives them their own way, and infatuates them in it. The error works with ever greater power in their souls, till they cannot imagine that it is an error; none can deliver himself, or say, Is there not a lie in my right hand? "My people would not hearken to My voice, and Israel would none of Me. So I gave them up unto their own hearts' lust: and they walked in their own counsels." "When they knew God, they glorified Him not as God, neither were thankful; ... wherefore God gave them up to uncleanness." "They changed the truth of God into a lie; ... for this cause God gave them up unto vile affections." "They did not like to retain God in their knowledge.... God gave them over to a reprobate mind." "They received not the love of the truth: and for this cause God sendeth unto them a working of error." Sin bears its punishment in itself; when it has had its perfect work, we see that it has been executing a judgment of God more awful than anything we could conceive. If you would have Him on your side, your ally and not your adversary, receive the love of the truth.
This is the final lesson of the passage. We do not know all the forces that are at work in the world in the interest of error; but we know there are many. We know that the mystery of iniquity is already in operation. We know that falsehood, in this spiritual sense, has much in man which is its natural ally; and that we need to be steadily on our guard against the wiles of the devil. We know that passion is sophistical, and reason often weak, and that we see our true selves in the action of heart and conscience. Be faithful, therefore, to God at the core of your nature. Love the truth that you may be saved. This alone is salvation. This alone is a safeguard against all the delusions of Satan; it was one who knew God, who lived in God, who did always the works of God, who loved God as the only begotten Son the Father, who could say, "The prince of this world cometh, and hath nothing in Me."
