There are persons with a diseased imagination to whom religion is a tyrant, ruling them as with a rod of iron. Such are constantly mourning over their depravity and groaning over supposed evil. Love does not exist in their hearts; a frown is ever upon their countenances. They are chilled by the innocent laugh from the youth or from anyone. They consider all recreation or amusement a sin and think that the mind must be constantly wrought up to just such a stern, severe pitch. This is one extreme. Others think that the mind must be ever on the stretch to invent new amusements and diversions in order to gain health. They learn to depend on excitement, and are uneasy without it. Such are not true Christians. They go to another extreme. 1TT 178.1
The true principles of Christianity open before all a source of happiness, the height and depth, the length and breadth of which are immeasurable. It is Christ in us a well of water springing up into everlasting life. It is a continual wellspring from which the Christian can drink at will and never exhaust the fountain. 1TT 178.2
That which brings sickness of body and mind to nearly all is dissatisfied feelings and discontented repinings. They have not God, they have not the hope which reaches to that within the veil, which is as an anchor to the soul both sure and steadfast. All who possess this hope will purify themselves even as He is pure. Such are free from restless longings, repinings, and discontent; they are not continually looking for evil and brooding over borrowed trouble. But we see many who are having a time of trouble beforehand; anxiety is stamped upon every feature; they seem to find no consolation, but have a continual fearful looking for of some dreadful evil. 1TT 178.3
Such dishonor God, and bring the religion of Christ into disrepute. They have not true love for God, nor for their companions and children. Their affections have become morbid. But vain amusements will never correct the minds of such. They need the transforming influence of the Spirit of God in order to be happy. 1TT 179.1

The sympathy which exists between the mind and the body is very great. When one is affected, the other responds. The condition of the mind has much to do with the health of the physical system. If the mind is free and happy, under a consciousness of rightdoing and a sense of satisfaction in causing happiness to others, it will create 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 healer, and those who are abundant in benefiting others will realize that wondrous blessing in their hearts and lives.—1876, Testimonies for the Church 4:60, 61. 1TT 179.2

The religion of the Bible is not detrimental to the health of the body or of the mind. The influence of the Spirit of God is the very best medicine that can be received by a sick man or woman. Heaven is all health, and the more deeply the heavenly influences are realized the more sure will be the recovery of the believing invalid.—1872, Testimonies for the Church 3:172. 1TT 179.3

Satan is the originator of disease; and the physician is warring against his work and power. Sickness of the mind prevails everywhere. Nine tenths of the diseases from which men suffer have their foundation here. Perhaps some living home trouble is, like a canker, eating to the very soul and weakening the life forces. Remorse for sin sometimes undermines the constitution and unbalances the mind. There are erroneous doctrines also, as that of an eternally burning hell and the endless torment of the wicked, that, by giving exaggerated and distorted views of the character of God, have produced the same result upon sensitive minds. Infidels have made the most of these unfortunate cases, attributing insanity to religion; but this is a gross libel and one which they will not be pleased to meet by and by. The religion of Christ, so far from being the cause of insanity, is one of its most effectual remedies; for it is a potent soother of the nerves.—1885, Testimonies for the Church 5:444. 1TT 179.4

The burden of sin, with its unrest and unsatisfied desires, lies at the very foundation of a large share of the maladies the sinner suffers. Christ is the mighty healer of the sin-sick soul. These poor afflicted ones need to have a clearer knowledge of Him whom to know aright is life eternal. They need to be patiently and kindly yet earnestly taught how to throw open the windows of the soul and let the sunlight of God's love come in to illuminate the darkened chambers of the mind.—1881, Testimonies for the Church 4:579. 1TT 180.1
