Passage
But as he which hath called you is holy, so be ye holy in all manner of conversation;
But as he which hath called you is holy, so be ye holy in all manner of conversation;
1 Peter 1:13 Wherefore gird up the loins of your mind, be sober, and hope to the end for the grace that is to be brought unto you at the revelation of Jesus Christ;
1 Peter 1:14 As obedient children, not fashioning yourselves according to the former lusts in your ignorance:
1 Peter 1:15 But as he which hath called you is holy, so be ye holy in all manner of conversation;
1 Peter 1:16 Because it is written, Be ye holy; for I am holy.
1 Peter 1:17 And if ye call on the Father, who without respect of persons judgeth according to every man’s work, pass the time of your sojourning here in fear:
The verse centers on "called", "hath", "holy", "manner", and "conversation". It is saying that the verse draws attention to "called" and "hath", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 14's "As obedient children not fashioning yourselves according..." into verse 16's "Because it is written Be ye holy...", so "called" and "hath" 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 "called" and "hath" with trust shaped by these words, not by a vague optimism outside the passage.
