Here is the quote on the picture, followed by some context (all-caps added for emphasis):
“There are but few as yet who are aroused sufficiently to understand how much their HABITS OF DIET have to do with their HEALTH, their CHARACTERS, their USEFULNESS IN THIS WORLD, and their ETERNAL DESTINY.” (Counsels on Diet and Foods, pp. 51,52, by Ellen G. White)
“Some have sneered at this work of reform, and have said it was all unnecessary; that it was an excitement to divert minds from present truth. They have said that matters were being carried to extremes. Such do not know what they are talking about. While men and women professing godliness are diseased from the crown of their head to the soles of their feet, while their physical, mental, and moral energies are enfeebled through gratification of depraved appetite and excessive labor, how can they weigh the evidences of truth, and comprehend the requirements of God? If their moral and intellectual faculties are beclouded, they cannot appreciate the value of the atonement or the exalted character of the work of God, nor delight in the study of His word. How can a nervous dyspeptic be ready always to give an answer to every man that asketh him a reason of the hope that is in him, with meekness and fear? How soon would such a one become confused and agitated, and by his diseased imagination be led to view matters in altogether a wrong light, and by a lack of that meekness and calmness which characterized the life of Christ, be caused to dishonor his profession while contending with unreasonable men? Viewing matters from high religious standpoint, we must be thorough reformers in order to be Christlike.
“I saw that our heavenly Father has bestowed upon us the great blessing of light upon the health reform, that we may obey the claims which He has upon us, and glorify Him in our bodies and spirits, which are His, and finally stand without fault before the throne of God. Our faith requires us to elevate the standard, and take advance steps. While many question the course pursued by other health reformers, they, as reasonable men, should do something themselves. Our race is in a deplorable condition, suffering from disease of every description. Many have inherited disease, and are great sufferers because of the wrong habits of their parents; and yet they pursue the same wrong course in regard to themselves and their children which was pursued toward them. They are ignorant in regard to themselves. They are sick and do not know that their own wrong habits are causing them immense suffering.
“THERE ARE BUT FEW AS YET WHO ARE AROUSED SUFFICIENTLY TO UNDERSTAND HOW MUCH THEIR HABITS OF DIET HAVE TO DO WITH THEIR HEALTH, THEIR CHARACTERS, THEIR USEFULNESS IN THIS WORLD, AND THEIR ETERNAL DESTINY. I saw that it is the duty of those who have received the light from heaven, and have realized the benefit of walking in it, to manifest a greater interest for those who are still suffering for want of knowledge. Sabbathkeepers who are looking for the soon appearing of their Saviour should be the last to manifest a lack of interest in this great work of reform. Men and women must be instructed, and ministers and people should feel that the burden of the work rests upon them to agitate the subject, and urge it home upon others.” (Counsels on Diet and Foods, pp. 50-52, by Ellen G. White)
