68. Physical habits have a great deal to do with the success of every individual. The more careful you are in your diet, the more simple and unstimulating the food that sustains the body in its harmonious action, the more clear will be your conception of duty. There needs to be a careful review of every habit, every practice, lest a morbid condition of the body shall cast a cloud upon everything.—Letter 93, 1898 (CD 52.1) MC VC

69. Our physical health is maintained by that which we eat; if our appetites are not under the control of a sanctified mind, if we are not temperate in all our eating and drinking, we shall not be in a state of mental and physical soundness to study the word with a purpose to learn what saith the Scripture—what shall I do to inherit eternal life? Any unhealthful habit will produce an unhealthful condition in the system, and the delicate, living machinery of the stomach will be injured, and will not be able to do its work properly. The diet has much to do with the disposition to enter into temptation and commit sin.—Manuscript 129, 1901 (CD 52.2) MC VC

70. If the Saviour of men, with His divine strength, felt the need of prayer, how much more should feeble, sinful mortals feel the necessity of prayer—fervent, constant prayer! When Christ was the most fiercely beset by temptation, He ate nothing. He committed Himself to God, and through earnest prayer, and perfect submission to the will of His Father, came off conqueror. Those who profess the truth for these last days, above every other class of professed Christians, should imitate the great Exemplar in prayer. (CD 52.3) MC VC
