R.A. Torrey, The Person and Work of the Holy Spirit, p.170
God by His Holy Spirit does impart new health and vigour to these mortal bodies in the present life. To go to the extremes that many do and take the ground that the believer who is walking in fellowship with Christ need never be ill is to go farther than the Bible warrants us in going. It is true that the redemption of our bodies is secured by the atoning work of Christ but until the Lord comes, we only enjoy the first fruits of that redemption; and we are waiting and sometimes groaning for our full place as sons manifested in the redemption of our body (Rom. viii. 23).
