Passage
always learning, and never to a knowledge of truth able to come,
always learning, and never to a knowledge of truth able to come,
2 Timothy 3:5 having a form of piety, and its power having denied; and from these be turning away,
2 Timothy 3:6 for of these there are those coming into the houses and leading captive the silly women, laden with sins, led away with desires manifold,
2 Timothy 3:7 always learning, and never to a knowledge of truth able to come,
2 Timothy 3:8 and, even as Jannes and Jambres stood against Moses, so also these do stand against the truth, men corrupted in mind, disapproved concerning the faith;
2 Timothy 3:9 but they shall not advance any further, for their folly shall be manifest to all, as theirs also did become.
The verse centers on "always", "learning", "never", "knowledge", "truth", "able", and "come". It is saying that the verse draws attention to "always" and "learning", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 6's "for of these there are those coming..." into verse 8's "and even as Jannes and Jambres stood...", so "always" and "learning" belong inside that flow. In 2 Timothy context, the local focus is Christ, faith, and discipleship.
A plain takeaway is to answer the verse's own emphasis on "always" and "learning" with trust shaped by these words, not by a vague optimism outside the passage.
