Passage
[men] who as to the truth have gone astray, saying that the resurrection has taken place already; and overthrow the faith of some.
[men] who as to the truth have gone astray, saying that the resurrection has taken place already; and overthrow the faith of some.
2 Timothy 2:16 But profane, vain babblings shun, for they will advance to greater impiety,
2 Timothy 2:17 and their word will spread as a gangrene; of whom is Hymenaeus and Philetus;
2 Timothy 2:18 [men] who as to the truth have gone astray, saying that the resurrection has taken place already; and overthrow the faith of some.
2 Timothy 2:19 Yet the firm foundation of God stands, having this seal, [The] Lord knows those that are his; and, Let every one who names the name of [the] Lord withdraw from iniquity.
2 Timothy 2:20 But in a great house there are not only gold and silver vessels, but also wooden and earthen; and some to honour, and some to dishonour.
The verse centers on "faith", "gone astray", "truth", "saying", "resurrection", "taken", "place", and "already". It is saying that the verse draws attention to "faith" and "gone astray", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 17's "and their word will spread as a..." into verse 19's "Yet the firm foundation of God stands...", so "faith" and "gone astray" 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 "faith" and "gone astray" with trust shaped by these words, not by a vague optimism outside the passage.
