When the Holy Spirit sanctifies believers, he does a complete work in them. He puts into their minds, wills and hearts a gracious, supernatural principle which fills them with a holy desire to live to God. The whole life and being of holiness lies in this. This is the new creation.
John OwenThe mortification of indwelling sin remaining in our mortal bodies, that it may not have life and power to bring forth the works or deeds of the flesh is the constant duty of believers.
