It is not God's will that we should seclude ourselves from the world. But while in the world we should sanctify ourselves to God. We should not pattern after the world. We are to be in the world as a corrective influence, as salt that retains its savor. Among an unholy, impure, idolatrous generation, we are to be pure and holy, showing that the grace of Christ has power to restore in man the divine likeness. We are to exert a saving influence upon the world. CH 592.1
“This is the victory that overcometh the world, even our faith.” 1 John 5:4. The world has become a lazar house of sin, a mass of corruption. It knows not the children of God because it knows Him not. We are not to practice its ways or follow its customs. Continually we are to resist its lax principles. Christ said to His followers, “Let your light so shine before men, that they may see your good works, and glorify your Father which is in heaven.” Matthew 5:16. It is the duty of physicians and nurses to shine as lights amid the corrupting influences of the world. They are to cherish principles which the world cannot tarnish. CH 592.2
In order for the church to be healthy, it must be composed of healthy Christians. But in our churches and institutions there are many sickly Christians. The light which the Lord has given me is plainly expressed in the third chapter of Philippians. This chapter should be carefully read and studied. The lessons it contains should be practiced. CH 592.3
He who co-operates with the Great Physician will keep nerves, sinews, and muscles in the best condition of health. In order to do its work properly, the human machinery needs careful attention. The harmonious action of the different parts must be preserved. CH 592.4
