Being holy and sanctified is not what you think.

3 Blessed be the God and Father of our Lord Jesus Christ, who has blessed us in Christ with every spiritual blessing in the heavenly places,
4 even as he chose us in him before the foundation of the world, that we should be holy and blameless before him. In love
5 he predestined us for adoption to himself as sons through Jesus Christ, according to the purpose of his will,
6 to the praise of his glorious grace, with which he has blessed us in the Beloved.
7 In him we have redemption through his blood, the forgiveness of our trespasses, according to the riches of his grace,
8 which he lavished upon us, in all wisdom and insight
9 making known to us the mystery of his will, according to his purpose, which he set forth in Christ
10 as a plan for the fullness of time, to unite all things in him, things in heaven and things on earth. – Ephesians 1:3-10
