Passage
because it is written, “You shall be holy, for I am holy.”
because it is written, “You shall be holy, for I am holy.”
1 Peter 1:14 As obedient children, not being conformed to the former lusts which were yours in your ignorance,
1 Peter 1:15 but like the Holy One who called you, be holy yourselves also in all your conduct;
1 Peter 1:16 because it is written, “You shall be holy, for I am holy.”
1 Peter 1:17 And if you address as Father the One who impartially judges according to each one’s work, conduct yourselves in fear during the time of your sojourn,
1 Peter 1:18 knowing that you were not redeemed with corruptible things like silver or gold from your futile conduct inherited from your forefathers,
The verse centers on "written", "shall", and "holy". It is saying that the verse draws attention to "written" and "shall", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 15's "but like the Holy One who called..." into verse 17's "And if you address as Father the...", so "written" and "shall" 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 "written" and "shall" with trust shaped by these words, not by a vague optimism outside the passage.
