Passage
for Christ indeed has once suffered for sins, [the] just for [the] unjust, that he might bring us to God; being put to death in flesh, but made alive in [the] Spirit,
for Christ indeed has once suffered for sins, [the] just for [the] unjust, that he might bring us to God; being put to death in flesh, but made alive in [the] Spirit,
1 Peter 3:16 having a good conscience, that [as to that] in which they speak against you as evildoers, they may be ashamed who calumniate your good conversation in Christ.
1 Peter 3:17 For [it is] better, if the will of God should will it, to suffer [as] well-doers than [as] evildoers;
1 Peter 3:18 for Christ indeed has once suffered for sins, [the] just for [the] unjust, that he might bring us to God; being put to death in flesh, but made alive in [the] Spirit,
1 Peter 3:19 in which also going he preached to the spirits [which are] in prison,
1 Peter 3:20 heretofore disobedient, when the longsuffering of God waited in [the] days of Noah while the ark was preparing, into which few, that is, eight souls, were saved through water:
The verse centers on "Spirit", "christ", "indeed", "once", "suffered", "sins", "just", and "unjust". It is saying that the verse draws attention to "Spirit" and "christ", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 17's "For it is better if the will..." into verse 19's "in which also going he preached to...", so "Spirit" and "christ" 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 "Spirit" and "christ" with trust shaped by these words, not by a vague optimism outside the passage.
