Passage
and ye <FI>are<Fi> a choice race, a royal priesthood, a holy nation, a people acquired, that the excellences ye may shew forth of Him who out of darkness did call you to His wondrous light;
and ye <FI>are<Fi> a choice race, a royal priesthood, a holy nation, a people acquired, that the excellences ye may shew forth of Him who out of darkness did call you to His wondrous light;
1 Peter 2:7 to you, then, who are believing <FI>is<Fi> the preciousness; and to the unbelieving, a stone that the builders disapproved of, this one did become for the head of a corner,
1 Peter 2:8 and a stone of stumbling and a rock of offence--who are stumbling at the word, being unbelieving, --to which also they were set;
1 Peter 2:9 and ye <FI>are<Fi> a choice race, a royal priesthood, a holy nation, a people acquired, that the excellences ye may shew forth of Him who out of darkness did call you to His wondrous light;
1 Peter 2:10 who <FI>were<Fi> once not a people, and <FI>are<Fi> now the people of God; who had not found kindness, and now have found kindness.
1 Peter 2:11 Beloved, I call upon <FI>you<Fi> , as strangers and sojourners, to keep from the fleshly desires, that war against the soul,
The verse centers on "light", "darkness", "choice", "race", "royal", "priesthood", "holy", and "nation". It is saying that the contrast between light and darkness marks a real divide in how people respond to God's work.
The nearby context moves from verse 8's "and a stone of stumbling and a..." into verse 10's "who FI were Fi once not a...", so "light" and "darkness" 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 "light" and "darkness" with trust shaped by these words, not by a vague optimism outside the passage.
