“Beloved, I wish above all things that you may prosper and be in health, even as your soul prospers.” 3 John 2.
A noble character is not the result of accident; it is not due to special favors or endowments of Providence. It is the result of self-discipline, of subjection of the lower to the higher nature, of the surrender of self to the service of God and man. …
The body is a most important medium through which the mind and the soul are developed for the upbuilding of character. Hence it is that the adversary of souls directs his temptations to the enfeebling and degrading of the physical powers. His success here often means the surrender of the whole being to evil. The tendencies of the physical nature, unless under the dominion of a higher power, will surely work ruin and death. The body is to be brought into subjection to the higher powers of the being. The passions are to be controlled by the will, which is itself to be under the control of God. The kingly power of reason, sanctified by divine grace, is to bear sway in the life. Intellectual power, physical stamina, and the length of life depend upon immutable laws. Through obedience to these laws, man may stand conqueror of himself, conqueror of his own inclinations, conqueror of principalities and powers, of “the rulers of the darkness of this world,” and of “spiritual wickedness in high places.” Ephesians 6:12. –Prophets and Kings, p. 488.
True education is the preparation of the physical, mental, and moral powers for the performance of every duty; it is the training of body, mind, and soul for divine service. This is the education that will endure unto eternal life. –Christ’s Object Lessons, p. 330.
