Sanctification (or in its verb form, sanctify) literally means "to set apart for special use or purpose", that is, to make holy or sacred (compare Latin: sanctus). Therefore, sanctification refers to the state or process of being set apart, i.e. "made holy", as a vessel, full of the Holy Spirit of God. The concept of sanctification is widespread among religions, including Judaism and especially Christianity. The term can be used to refer to objects which are set apart for special purposes, but the most common use within Christian theology is in reference to the change brought about by God in a believer, begun at the point of salvation and continuing throughout the life of the believer. Many forms of Christianity believe that this process will only be completed in Heaven, but some believe that complete holiness is possible in this life.
