2 Thessalonians 2:11

And for this cause God shall send them strong delusion,.... Or "efficacy of error", which God may be said to send; and the Alexandrian copy reads, "does send"; because it is not a bare permission but a voluntary one; or it is his will that error should be that truth may be tried, and be illustrated by its contrary, and shine the more through the force of opposition to it; and that those which are on the side of it might be made manifest, as well as that the rejecters of the Gospel might be punished; for the efficacy of error is not to be considered as a sin, of which God cannot be the author, but as a punishment for sin, and to which men are given up, and fall under the power of, because they receive not the love of the truth, which is the reason here given: and this comes to pass partly through God's denying his grace, or withholding that light and knowledge, by which error may be discovered and detected; and by taking from men the knowledge and conscience of things they had, see Romans 1:28. So that they call evil good, and good evil, and do not appear to have the common sense and reason of mankind, at least do not act according to it; and by giving them up to judicial blindness and hardness of heart, and to the god of this world, to blind their minds; and without this it is not to be accounted for, that the followers of antichrist should give into such senseless notions as those of transubstantiation, works of supererogation, c., or into such stupid practices as worshipping of images, praying to saints departed, and paying such a respect to the pretended relics of saints, c., as they do but a spirit of slumber is given them, and eyes that they should not see, and ears that they should not hear, because of their rejection of the Gospel: and

that they should believe a lie that the pope is Christ's vicar on earth, and has power to forgive sins; that the bread and wine in the Lord's supper are transubstantiated into the very body and blood of Christ; with other lying tenets spoken in hypocrisy concerning good works, merit, pardon, penance; c. with a multitude of lying wonders and false miracles, of which their legends are full and this is the first and more near end of strong delusion or efficacious error being sent them; the more remote and ultimate one follows.
