Those who engage in sanitarium work should have a treasure house full of rich experience, because the truth is implanted in the heart, and as a holy thing is tended and fed by the grace of God. Rooted and grounded in the truth, they should have a faith that works by love and purifies the soul. Constantly asking for blessings, they should keep the windows of the soul closed earthward against the malarious atmosphere of the world, and opened heavenward to receive the bright beams of the Sun of Righteousness. CH 252.1
Who is preparing to take hold understandingly of medical missionary work? By this work the minds of those who come to our sanitariums for treatment are to be led to Christ and taught to unite their weakness with His strength. Every worker should be understandingly efficient. Then in a high, broad sense he can present the truth as it is in Jesus. CH 252.2
The workers in our sanitariums are continually exposed to temptation. They are brought in contact with unbelievers, and those who are not sound in the faith will be harmed by the contact. But those who are abiding in Christ will meet unbelievers as He met them, refusing to be drawn from their allegiance, but always ready to speak a word in season, always ready to sow the seeds of truth. They will watch unto prayer, firmly maintaining their integrity, and daily showing the consistency of their religion. The influence of such workers is a blessing to many. By a well-ordered life they draw souls to the cross. A true Christian constantly acknowledges Christ. He is always cheerful, always ready to speak words of hope and comfort to the suffering. CH 252.3
“The fear of the Lord is the beginning of knowledge.” Proverbs 1:7. One sentence of Scripture is of more value than ten thousand of man's ideas or arguments. Those who refuse to follow God's way will finally receive the sentence, “Depart from Me.” But when we submit to God's way, the Lord Jesus guides our minds and fills our lips with assurance. We may be strong in the Lord and in the power of His might. Receiving Christ, we are clothed with power. An indwelling Saviour makes His power our property. The truth becomes our stock in trade. No unrighteousness is seen in the life. We are able to speak words in season to those who know not the truth. Christ's presence in the heart is a vitalizing power, strengthening the entire being. CH 253.1
