Great peace have they which love thy law: and nothing shall offend them. Psalm 119:165.

If the mind is free and happy, from a consciousness of rightdoing and a sense of satisfaction in causing happiness to others, it creates a cheerfulness that will react upon the whole system, causing a freer circulation of the blood and a toning up of the entire body. The blessing of God is a healing power, and those who are abundant in benefiting others will realize that wondrous blessing in both heart and life.^{116Christian Temperance and Bible Hygiene, 13.}

Those who follow the path of wisdom and holiness will not be troubled with vain regrets over misspent hours, neither will they be troubled with gloom or horror of mind, as some are, unless engaged in vain, trifling amusements….

Amusements excite the mind, but depression is sure to follow. Useful labor and physical exercise will have a more healthful influence upon the mind and will strengthen the muscles, improve the circulation, and will prove a powerful agent in the recovery of health….

The consciousness of rightdoing is the best medicine for diseased bodies and minds. The special blessing of God resting upon the receiver is health and strength.^{117The Health Reformer, March 1872.}

Doing good is a work that benefits both giver and receiver. If you forget self in your interest for others, you gain a victory over your infirmities. The satisfaction you will realize in doing good will greatly aid you in the recovery of the healthy tone of the imagination. The pleasure of doing good animates the mind and vibrates through the whole body.^{118Testimonies for the Church 2:534.}

A person whose mind is quiet and satisfied in God is in the pathway to health.^{119The Review and Herald, March 11, 1880.}
