In regard to that which we can do for ourselves: There is a point that requires careful, thoughtful consideration. I must become acquainted with myself. I must be a learner always as to how to take care of this building, the body God has given me, that I may preserve it in the very best condition of health. I must eat those things which will be for my very best good physically, and I must take special care to have my clothing such as will conduce to a healthful circulation of the blood. I must not deprive myself of exercise and air. I must get all the sunlight that it is possible for me to obtain. I must have wisdom to be a faithful guardian of my body. MM 230.1
I should do a very unwise thing to enter a cool room when in a perspiration; I should show myself an unwise steward to allow myself to sit in a draft and thus expose myself so as to take cold. I should be unwise to sit with cold feet and limbs and thus drive back the blood from the extremities to the brain or internal organs. I should always protect my feet in damp weather. I should eat regularly of the most healthful food which will make the best quality of blood, and I should not work intemperately if it is in my power to avoid doing so. And when I violate the laws God has established in my being, I am to repent and reform, and place myself in the most favorable condition under the doctors God has provided—pure air, pure water, and the healing, precious sunlight. MM 230.2
If we neglect to do that which is within the reach of nearly every family, and ask the Lord to relieve pain when we are too indolent to make use of these remedies within our power, it is simply presumption. The Lord expects us to work in order that we may obtain food. He does not propose that we shall gather the harvest unless we break the sod, till the soil, and cultivate the produce. Then God sends the rain and the sunshine and the clouds to cause vegetation to flourish. God works and man cooperates with God. Then there is seedtime and harvest. God has caused to grow out of the ground herbs for the use of man, and if we understand the nature of these roots and herbs, and make a right use of them, there would not be a necessity of running for the doctor so frequently, and people would be in much better health than they are today.—Letter 35, 1890.
