“As obedient children do not conduct yourselves according to the former lusts in your ignorance. But as He who has called you is holy, so be holy in all your conduct, because it is written, “Be holy, for I am holy” — 1 Peter 1:14-16
Holiness is the choice to march to the beat of a different drum. Rather than to live as our culture encourages us to, we must live as God requires. If we are not to be conformed to this world (see Romans 12:1-2), neither are we to be conformed to our former desires.
