Disease is sometimes produced, and is often greatly aggravated, by the imagination. Many are lifelong invalids who might be well if they only thought so. . . .
Courage, hope, faith, sympathy, love, promote health and prolong life. A contented mind, a cheerful spirit, is health to the body and strength to the soul.
Gratitude, rejoicing, benevolence, trust in God's love and care-- these are health's greatest safeguard.
The power of the will and the importance of self-control, both in the preservation and in the recovery of health, the depressing and even ruinous effect of anger, discontent, selfishness, or impurity, and, on the other hand, the marvelous life-giving power to be found in cheerfulness, unselfishness, gratitude, should also be shown.
There is a physiological truth--truth that we need to consider-- in the scripture, "A merry {rejoicing} heart doeth good like a medicine."
The true principles of Christianity open before all a source of inestimable happiness.
We should encourage a cheerful, hopeful, peaceful frame of mind; for our health depends upon our so doing. ML 151
The simple prayers indited by the Holy Spirit will ascend through the gates ajar, the open door which Christ has declared: I have opened, and no man can shut. These prayers, mingled with the incense of the perfection of Christ, will ascend as fragrance to the Father, and answers will come. Pr 46-47
A merry heart doeth good like a medicine: but a broken spirit drieth the bones. Proverbs 17:22 (King James Version)
