Sin brings physical and spiritual disease and weakness. Christ has made it possible for us to free ourselves from this curse. The Lord promises, by the medium of truth, to renovate the soul. The Holy Spirit will make all who are willing to be educated able to communicate the truth with power. It will renew every organ of the body, that God's servants may work acceptably and successfully. Vitality increases under the influence of the Spirit's action. Let us, then, by this power lift ourselves into a higher, holier atmosphere, that we may do well our appointed work. 1NL 131.8
By constant obedience those who are born again are fitted for service. The entire being is to be placed under the molding, fashioning hand of God, that physical, mental, and spiritual perfection may be attained. Christians are to grow to the full stature of men and women in Christ. 1NL 132.1
