I get the logic of what you are saying, but I think you are mistaken. Here is 2 Timothy chapter 3 in its entirety. Isn’t it interesting that the men chosen by Paul as an example of those who oppose the truth where two men known for performing signs and wonders??
2 Timothy 3:1-17 KJV
[1] This know also, that in the last days perilous times shall come.
[2] For men shall be lovers of their own selves, covetous, boasters, proud, blasphemers, disobedient to parents, unthankful, unholy,
[3] Without natural affection, trucebreakers, false accusers, incontinent, fierce, despisers of those that are good,
[4] Traitors, heady, highminded, lovers of pleasures more than lovers of God;
[5] Having a form of godliness, but denying the power thereof: from such turn away.
[6] For of this sort are they which creep into houses, and lead captive silly women laden with sins, led away with divers lusts,
[7] Ever learning, and never able to come to the knowledge of the truth.
[8] Now as Jannes and Jambres withstood Moses, so do these also resist the truth: men of corrupt minds, reprobate concerning the faith.
[9] But they shall proceed no further: for their folly shall be manifest unto all men , as theirs also was. [10] But thou hast fully known my doctrine, manner of life, purpose, faith, longsuffering, charity, patience,
[11] Persecutions, afflictions, which came unto me at Antioch, at Iconium, at Lystra; what persecutions I endured: but out of them all the Lord delivered me. [12] Yea, and all that will live godly in Christ Jesus shall suffer persecution.
[13] But evil men and seducers shall wax worse and worse, deceiving, and being deceived.
[14] But continue thou in the things which thou hast learned and hast been assured of, knowing of whom thou hast learned them ;
[15] And that from a child thou hast known the holy scriptures, which are able to make thee wise unto salvation through faith which is in Christ Jesus.
[16] All scripture is given by inspiration of God, and is profitable for doctrine, for reproof, for correction, for instruction in righteousness:
[17] That the man of God may be perfect, throughly furnished unto all good works.
