There are those who will suggest to you that in order to be successful in your profession you must be a policy man; you must at times depart from strict rectitude. These temptations find a ready welcome in the heart of man; but I speak that which I know. Do not be deceived or deluded. Do not pamper self. Do not throw open a door through which the enemy may enter to take possession of the soul. There is danger in the first and slightest departure from the strictest rectitude. Be true to yourself. Preserve your God-given dignity in the fear of God. There is great need that every medical worker get hold and keep hold of the arm of Infinite Power. MM 128.2
The policy principle is one that will assuredly lead into difficulties. He who regards the favor of men as more desirable than the favor of God will fall under the temptation to sacrifice principle for worldly gain or recognition. Thus fidelity to God is constantly being sacrificed. Truth, God's truth, must be cherished in the soul and held in the strength of heaven, or the power of Satan will wrest it from you. MM 128.3
Never entertain the thought that an honest, truthful physician cannot succeed. Such a sentiment dishonors the God of truth and righteousness. He can succeed; for he has God and heaven on his side. Let every bribe to dissimulate be sternly refused. Hold fast your integrity in the strength of the grace of Christ, and He will fulfill His word to you.—Counsels to Parents, Teachers, and Students, 485-486 MM 128.4
