1 Peter 2:9
But you people are especially chosen [by God]; you are a royal body of priests; you are a nation especially set apart for God's use; you are a people who belong exclusively to God, that you may express the virtues of the One who called you out of darkness [i.e., of sin and error], and into His marvelous light [i.e., righteousness and truth].
