1 Corinthians 1:31
So, as it is written [Jer. 9:23f], "The person who [wants to] boast, let him boast about the Lord."

And you yourselves are also like living stones, being constructed into a spiritual house. For you are like holy priests who offer spiritual sacrifices that are acceptable to God through Jesus Christ.
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].
