What kind of people will accept the Antichrist?
Those who accept the Antichrist are unbelievers who heard the gospel and the truth of God's Word but loved unrighteousness, rejected it, and spurned God's offer of salvation. Because they refused the love of the truth, God sends them a strong delusion to believe the lie.
Les explains that the Antichrist's coming is after the working of Satan, with power, signs, lying wonders, and all deceivableness of unrighteousness in them that perish—that is, the unbeliever. The people ready to accept him are those who had an opportunity to hear the gospel, the truth of the Word of God, but loved their unrighteousness, rejected it, and spurned God's offer of salvation. Because they received not the love of the truth that they might be saved, God sends them a strong delusion, that they should believe the lie.
And with all deceivableness of unrighteousness in them that perish; because they received not the love of the truth, that they might be saved.
