But wicked men and impostors This is the most bitter of all persecutions, when we see wicked men, with their sacrilegious hardihood, with their blasphemies and errors, gathering strength. Thus Paul says elsewhere, that Ishmael persecuted Isaac, not by the sword, but by mockery (Galatians 4:29.) Hence also we may conclude, that in the preceding verse, it was not merely one kind of persecution that was described, but that the Apostle spoke, in general terms, of those distresses which the children of God are compelled to endure, when they contend for the glory of their Father. I stated, a little before, in what respect they shall grow worse and worse; for he foretells not only that they will make obstinate resistance, but that they will succeed in injuring and corrupting others. One worthless person will always be more effectual in destroying, than ten faithful teachers in building, though they labor with all their might. Nor are there ever wanting the tares which Satan sows for injuring the pure corn; and even when we think that false prophets are driven away, others continually spring up in other directions. Again, as to the power of doing injury, [1] it is not because falsehood, in its own nature, is stronger than truth, or that the tricks of Satan exceed the energy of the Spirit of God; but because men, being naturally inclined to vanity and errors, embrace far more readily what agrees with their natural disposition, and also because, being blinded by a righteous vengeance of God, they are led, as captive slaves, at the will of Satan. [2] And the chief reason, why the plague of wicked doctrines is so efficacious, is, that the ingratitude of men deserves that it should be so. It is highly necessary for godly teachers to be reminded of this, that they may be prepared for uninterrupted warfare, and may not be discouraged by delay, or yield to the haughtiness and insolence of adversaries.

But evil men and seducers shall wax worse and worse - That is, it is the character of such men to do this; they may be expected to do it. This is the general law of depravity - that if men are not converted, they are always growing worse, and sinking deeper into iniquity. Their progress will be certain, though it may be gradual, since "nemo repente turpissimus." The connection here is this: that Timothy was not to expect that he would be exempt from persecution 2-Timothy 3:12, by any change for the better in the wicked men referred to. He was to anticipate in them the operation of the general law in regard to bad men and seducers - that they would grow worse and worse. From this fact, he was to regard it as certain that he, as well as others, would be liable to be persecuted. The word rendered "seducers" - γόης goēs - occurs nowhere else in the New Testament. It means, properly, a "juggler, or diviner;" and then, a "deceiver, or impostor." Here it refers to those who by seductive arts, lead persons into error.
Deceiving - Making others believe that to be true and right, which is false and wrong. This was, of course, done by seductive arts.
And being deceived - Under delusion themselves. The advocates of error are often themselves as really under deception, as those whom they impose upon. They are often sincere in the belief of error, and then they are under a delusion; or, if they are insincere, they are equally deluded in supposing that they can make error pass for truth before God, or can deceive the Searcher of hearts. The worst victims of delusion are those who attempt to delude others.

Evil men and seducers shall wax worse - They will yet get on for a season, deceiving themselves and deceiving others; but, by and by, their folly will become manifest to all, 2-Timothy 3:9. The word γοητες, which we render seducers, signifies jugglers, pretenders to magical arts; probably persons dealing in false miracles, with whom the Church in all ages has been not a little disgraced.

But evil men and seducers shall wax (d) worse and worse, deceiving, and being deceived.
(d) Their wickedness will daily increase.

But evil men and seducers shall wax worse and worse,.... By "evil men" are meant, not sinful men in common, as all are by nature and practice; nor only open profane sinners but rather wicked men under a form of godliness, as before; and who are full of wickedness and malice against truly godly persons, even as the devil himself, of whom the same word is used, when he is called the wicked one; and this is a reason why true professors of religion must expect persecution, seeing as there ever were, so there ever will be such sort of men, who will not grow better, but worse and worse. The word for "seducers", signifies sorcerers, enchanters, a sort of jugglers; and as the other, it well suits with the ecclesiastics of the church of Rome, who pretend to miracles, and do lying wonders, and by their sorceries deceive all nations, Revelation 18:23 and these "shall wax worse and worse"; in principle and in practice, in ungodliness, and in error, in wickedness and malice against the saints, and in the arts of deceiving; so the church of Rome is never to be expected to be better, but worse; at the time of the fall of Babylon she will be an habitation of devils, the hold of every foul spirit, and the cage of every unclean and hateful bird, Revelation 18:2
deceiving: not God, but themselves and others even all nations, excepting the elect of God; which they do by their good words and fair speeches, and by their show of devotion and religion, and by their pretended miracles and lying wonders:
and deceived by the old serpent, the devil, under whose power and influence they are, in whose snare they are taken, and by whom they are led captive, and will at last share the same fate with himself, and be cast into the same lake of fire and brimstone.

Reason why persecutions must be expected, and these becoming worse and worse as the end approaches. The breach between light and darkness, so far from being healed, shall be widened [ALFORD].
evil men--in contrast to the "godly" (2-Timothy 3:12).
seducers--literally, "conjurers." Magical arts prevailed at Ephesus (Acts 19:19), and had been renounced by many Ephesians on embracing Christianity: but now when Paul was writing to Ephesus, symptoms of a return to conjuring tricks appeared: an undesigned coincidence [BURTON]. Probably sorcery will characterize the final apostasy (Revelation 13:15; Revelation 18:23; Revelation 22:15).
wax worse--literally, "advance in the direction of worse" (see on 2-Timothy 3:9). Not contradictory to that verse: there the diffusion of the evil was spoken of; here its intensity [ALFORD].
deceiving, and being deceived--He who has once begun to deceive others, is the less easily able to recover himself from error, and the more easily embraces in turn the errors of others [BENGEL].

Deceiving and being deceived - He who has once begun to deceive others is both the less likely to recover from his own error, and the more ready to embrace the errors of other men.
