Passage
as obedient children, not fashioning yourselves to the former desires in your ignorance,
as obedient children, not fashioning yourselves to the former desires in your ignorance,
1 Peter 1:12 to whom it was revealed, that not to themselves, but to us they were ministering these, which now were told to you (through those who did proclaim good news to you,) in the Holy Spirit sent from heaven, to which things messengers do desire to bend looking.
1 Peter 1:13 Wherefore having girded up the loins of your mind, being sober, hope perfectly upon the grace that is being brought to you in the revelation of Jesus Christ,
1 Peter 1:14 as obedient children, not fashioning yourselves to the former desires in your ignorance,
1 Peter 1:15 but according as He who did call you <FI>is<Fi> holy, ye also, become holy in all behaviour,
1 Peter 1:16 because it hath been written, `Become ye holy, because I am holy;'
The verse centers on "obedient", "children", "fashioning", "yourselves", "former", "desires", and "ignorance". It is saying that the verse draws attention to "obedient" and "children", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 13's "Wherefore having girded up the loins of..." into verse 15's "but according as He who did call...", so "obedient" and "children" 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 "obedient" and "children" with trust shaped by these words, not by a vague optimism outside the passage.
