At the cost of infinite sacrifice and suffering, Christ has provided for us every essential to success in the Christian warfare. The Holy Spirit brings power that enables man to overcome. It is through the agency of the Spirit that the government of Satan is to be subdued. It is the Spirit that convinces of sin, and, with the consent of the human being, expels sin from the heart. The mind is then brought under a new law—the royal law of liberty. (OHC 152.3) MC VC
