2-timothy 3:9

Manifest - To make openly known; appear.

But they shall proceed no farther - Such teaching and teachers shall never be able ultimately to prevail against the truth; for the foundation of God standeth sure.

Their folly shall be manifest - As the Scriptures, which are the only rule of morals and doctrine, shall ever be preserved; so, sooner or later, all false doctrines shall be tried by them: and the folly of men, setting up their wisdom against the wisdom of God, must become manifest to all. False doctrine cannot prevail long where the sacred Scriptures are read and studied. Error prevails only where the book of God is withheld from the people. The religion that fears the Bible is not the religion of God. Is Popery or Protestantism this religion?

But they shall proceed no further - There is a certain point beyond which they will not be allowed to go. Their folly will become manifest, and the world will understand it. The apostle does not say how far these false teachers would be allowed to go, but that they would not be suffered always to prosper and prevail. They might be plausible at first, and lead many astray; they might, by art and cunning, cover up the real character of their system; but there would be a fair development of it, and it would be seen to be folly. The apostle here may be understood as declaring a general truth in regard to error. It often is so plausible at first, that it seems to be true. It wins the hearts of many persons, and leads them astray. It flatters them personally, or it flatters them with the hope of a better state of things in the church and the world. But the time will always come when men will see the folly of it. Error will advance only to a certain point, when it will be "seen" to be falsehood and folly, and when the world will arise and cast it off. In some cases, this point may be slower in being reached than in others; but there "is" a point, beyond which error will not go. At the reformation under Luther, that point had been reached, when the teachings of the great apostasy were seen to be "folly," and when the awakened intellect of the world would allow it to "proceed no farther," and aroused itself and threw it off. In the workings of society, as well as by the direct appointment of God, there is a point beyond which error cannot prevail; and hence, there is a certainty that truth will finally triumph.

For their folly shall be manifest unto all men - The world will see and understand what they are, and what they teach. By smooth sophistry, and cunning arts, they will not be able always to deceive mankind.

As their's also was - That of Jannes and Jambres. That is, it became manifest to all that they could not compete with Moses and Aaron; that their claims to the power of working miracles were the mere arts of magicians, and that they had set up pretensions which they could not sustain; compare Exodus 8:18-19. In regard to the time to which the apostle referred in this description, it has already been observed (see the notes at 2 Timothy 3:1), that it was probably to that great apostasy of the "latter days," which he has described in 2 Thessalonians 2:and 1 Timothy 4:But there seems to be no reason to doubt that he had his eye immediately on some persons who had appeared then, and who had evinced some of the traits which would characterize the great apostasy, and whose conduct showed that the great "falling away" had already commenced. In 2 Thessalonians 2:7, he says that the "mystery of iniquity" was already at work, or was even then manifesting itself; and there can be no doubt that the apostle saw that there had then commenced what he knew would yet grow up into the great defection from the truth. In some persons, at that time, who had the form of godliness, but who denied its power; who made use of insinuating arts to proselyte the weak and the credulous; who endeavor to imitate the true apostles, perhaps by attempting to work miracles, as Jannes and Jambres did, he saw the "germ" of what was yet to grow up into so gigantic a system of iniquity as to overshadow the world. Yet he consoled Timothy with the assurance that there was a point beyond which the system of error would not be allowed to go, but where its folly must be seen, and where it would be arrested.

3:9 They shall proceed no farther - In gaining proselytes.
