John 15:19
If you belonged to the world, the world would love [you as] its own people. But since you do not belong to the world, for I chose you out of it, that is why the world hates you.
2 Corinthians 6:17
Therefore, the Lord says [Isa. 52:11], "You people should leave their company [i.e., unbelievers, verse 14] and separate yourselves from them, and do not touch anything unclean [i.e., their evil practices], and I will welcome you."
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].
