Passage
having known that, not with corruptible things--silver or gold--were ye redeemed from your foolish behaviour delivered by fathers,
having known that, not with corruptible things--silver or gold--were ye redeemed from your foolish behaviour delivered by fathers,
1 Peter 1:16 because it hath been written, `Become ye holy, because I am holy;'
1 Peter 1:17 and if on the Father ye do call, who without acceptance of persons is judging according to the work of each, in fear the time of your sojourn pass ye,
1 Peter 1:18 having known that, not with corruptible things--silver or gold--were ye redeemed from your foolish behaviour delivered by fathers,
1 Peter 1:19 but with precious blood, as of a lamb unblemished and unspotted--Christ's--
1 Peter 1:20 foreknown, indeed, before the foundation of the world, and manifested in the last times because of you,
The verse centers on "having", "known", "corruptible", "things--silver", "gold--were", "redeemed", "foolish", and "behaviour". It is saying that the verse draws attention to "having" and "known", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 17's "and if on the Father ye do..." into verse 19's "but with precious blood as of a...", so "having" and "known" belong inside that flow. In 1 Peter context, the local focus is hope in suffering, holy conduct, submission, and grace.
A plain takeaway is to answer the verse's own emphasis on "having" and "known" with trust shaped by these words, not by a vague optimism outside the passage.
