Exercising Self-control

But I keep under my body, and bring it into subjection: lest that by any means, when I have preached to others, I myself should be a castaway. 1 Corinthians 9:27 -- {ML 78.1}

The body is the only 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 means the surrender to evil of the whole being. The tendencies of our physical nature, unless under the dominion of a higher power, will surely work ruin and death. -- {ML 78.2}

The body is to be brought into subjection. The higher powers of the being are to rule. The passions are to be controlled by the will, which is itself to be under the control of God.... -- {ML 78.3}

The requirements of God must be brought home to the conscience. Men and women must be awakened to the duty of self-mastery, the need of purity, freedom from every depraving appetite and defiling habit. They need to be impressed with the fact that all their powers of mind and body are the gift of God, and are to be preserved in the best possible condition for His service.... -- {ML 78.4}

Human barriers against natural and cultivated tendencies are but as the sandbank against the torrent. Not until the life of Christ becomes a vitalizing power in our lives can we resist the temptations that assail us from within and from without.... By becoming one with Christ, man is free. Subjection to the will of Christ means restoration to perfect manhood. -- {ML 78.5}

Obedience to God is liberty from the thraldom of sin, deliverance from human passion and impulse. Man may stand conqueror of himself, conqueror of his own inclinations, conqueror of principalities and powers, and of "the rulers of the darkness of this world," and of "spiritual wickedness in high places." -- {ML 78.6}
