[Gospel Workers, 239-241 edition, (1915).]
I am pained at heart as I see so many feeble ministers, so many on beds of sickness, and so many closing the scenes of their earthly history—men who have carried the burden of responsibility in the work of God, whose whole heart was in their work. The conviction that they must cease their labor in the cause they loved was far more painful to them than their sufferings from disease, or even death itself. CH 563.1
Is it not time for us to understand that nature will not long suffer abuse without protesting? Our heavenly Father does not willingly afflict or grieve the children of men. He is not the author of sickness and death. He is the source of life; He would have men live, and He desires them to be obedient to the laws of life and health, that they may live. CH 563.2
Those who accept the present truth and are sanctified through it have an intense desire to represent the truth in their life and character. They have a deep yearning of soul that others may see the light and rejoice in it. As the true watchman goes forth, bearing precious seed, sowing beside all waters, weeping and praying, the burden of labor is very taxing to mind and heart. He cannot keep up the strain continuously, his soul stirred to the very depths, without wearing out prematurely. Strength and efficiency are needed in every discourse. And from time to time fresh supplies of things new and old need to be brought forth from the storehouse of God's word. This will impart life and power to the hearers. God does not want you to become so exhausted that your efforts have no freshness or life. CH 563.3
Those who are engaged in constant mental labor, whether in study or preaching, need rest and change. The earnest student is constantly taxing the brain, too often while neglecting physical exercise, and as the result the bodily powers are enfeebled and mental effort is restricted. Thus the student fails of accomplishing the very work that he might have done had he labored wisely. CH 563.4
