'Sanctified' in the Bible

To God’s church at Corinth, to those who are sanctified in Christ Jesus and called as saints, with all those in every place who call on the name of Jesus Christ our Lord—both their Lord and ours.

And some of you used to be like this. But you were washed, you were sanctified, you were justified in the name of the Lord Jesus Christ and by the Spirit of our God.

For the unbelieving husband is set apart for God by the wife, and the unbelieving wife is set apart for God by the husband. Otherwise your children would be corrupt, but now they are set apart for God.
