All physicians should place themselves under the control of the Great Physician. Under His guidance they will do as they should do. But the Lord will not work a miracle to save physicians who recklessly abuse His building. As far as possible, physicians should observe regularity in their habits of eating. They should take a proper amount of exercise. They should be determined to cooperate with the great Master Builder. God works, and man must come into line and work with Him; for He is the Saviour of the body. CH 588.3
Physicians, above all others, need to realize the relation human beings sustain toward God in regard to the preservation of health and life. They need to study the word of God diligently, lest they disregard the laws of health. There is no need for them to become weak and unbalanced. Under the guidance of the heavenly authority, they may advance in clear, straight lines. But they must give the most earnest heed to the laws of God. They should feel that they are the property of God, that they have been bought with a price, and that therefore they are to glorify Him in all things. By the study of God's word they are to keep the mind awake to the fact that human beings are the Lord's property by creation and by redemption. They are to say, I will do all in my power to save the souls and bodies of those for whom I work. They have been bought with a price, even the blood of Christ, and I must do all I can to help them. CH 588.4
The instruction I have for our physicians is that they must study the word of God with earnestness and diligence. God says, “Come out, ... and be ye separate, ... and touch not the unclean.” 2 Corinthians 6:17. Obey this word, at whatever cost to social position, worldly honor, or earthly wealth. Trust in the Lord. Walk in all humility of mind before Him. Holding by faith to His word, you may go forward. CH 589.1
