2 Thessalonians: Chapter 2, Verse 11

“And for this cause God shall send them strong delusion, &c.”

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.

John Gill

John Gill (1697-1771) was a Strict and Particular Baptist preacher and theologian. He was appointed the Pastor of Goat Yard Chapel, Horsleydown, Southwark, serving this position for fifty-one years. He was the first Baptist to write an exhaustive systematic theology, setting forth High-Calvinistic views and a clear Baptist polity which became the backbone for the churches subscribing to them. John Hazelton wrote of him:

”[Augustus] Toplady held in high regard Dr. John Gill (1697-1771), and applied to him and to his controversial writings what was said of the first Duke of Marlborough—that he never besieged a town that he did not take, nor fought a battle that he did not win. Gill's book on the Canticles is a beautiful and experimental exposition of Solomon's Song; his "Cause of God and Truth" is most admirable and suggestive; and his "Body of Divinity" one of the best of its kind. His commentary upon the Old and New Testament is a wonderful monument of sanctified learning, though it has been so used as to rob many a ministry of living power. It is the fashion now to sneer at Gill, and this unworthy attitude is adopted mostly by those who have forsaken the truths he so powerfully defended, and who are destitute of a tithe of the massive scholarship of one of the noblest ministers of the Particular and Strict Baptist denomination. The late Dr. Doudney rendered inestimable service by his republication, in 1852, of Gill's Commentary, printed at Bonmahon, Waterford, Ireland, by Irish boys. Gill was born at Kettering, and passed away at his residence at Camberwell, his last words being: "O, my Father! my Father!" For fifty-one years, to the time of his death, he was pastor of the Baptist Church, Fair Street, Horselydown, and was buried in Bunhill Fields. His Hebrew learning was equal to that of any scholar of his day, and his Rabbinical knowledge has never been equalled outside Judaism. His "Dissertation Concerning the Eternal Sonship of Christ" is most valuable, and this foundation truth is shown by him to have been a part of the faith of all Trinitarians for about 1,700 years from the birth of our Lord. In His Divine nature our blessed Lord was the co-equal and co-eternal Son of God, and as such He became the Word of God. The Scriptures nowhere intimate that Christ is the Son of God by office, or that His Sonship is founded on His human nature. This is not a strife about words, but is for our life, our peace, our hope. Dr. Gill's pastoral labours were much blest; to the utmost fidelity he united real tenderness, and at the Lord's Supper he was always at his best.
"He set before their eyes their dying Lord—
How soft, how sweet, how solemn every word!
How were their hearts affected, and his own!
And how his sparkling eyes with glory shone!"
