What does it mean to be sanctified in 1 Corinthians 6:11?

Les explains that in 1 Corinthians 6:11, Paul lists fornicators, idolaters, adulterers, the effeminate, abusers of themselves with mankind, thieves, the covetous, drunkards, revilers, and extortioners, saying none will inherit the kingdom of God. He then says, "and such were some of you, and now you are washed," meaning they have been cleansed of all their wickedness. "But you are sanctified," meaning they were now set apart for God's purposes. They are also justified, which is that judicial act of God whereby He declares the sinner just as if they had never sinned. God cleanses the idolater as though he had never fallen before an idol, justifies the drunkard as though he had never taken a drink, and justifies the adulterer as though he had never committed adultery. This is the beauty of salvation by grace. Les notes this is not merely a Pauline concept, for the Lord Jesus Himself uses the term in John's Gospel regarding the twelve or the eleven.
