You should keep off from Satan's enchanted ground and not allow your minds to be swayed from allegiance to God. Through Christ you may and should be happy and should acquire habits of self-control. Even your thoughts must be brought into subjection to the will of God and your feelings under the control of reason and religion. Your imagination was not given you to be allowed to run riot and have its own way without any effort at restraint or discipline. If the thoughts are wrong the feelings will be wrong, and the thoughts and feelings combined make up the moral character.... If you yield to your impressions and allow your thoughts to run in a channel of suspicion, doubt, and repining you will be among the most unhappy of mortals....
Dear Sister F, you have a diseased imagination; and you dishonor God by allowing your feelings to have complete control of your reason and judgment. You have a determined will, which causes the mind to react upon the body, unbalancing the circulation and producing congestion in certain organs; and you are sacrificing health to your feelings.
You are making a mistake, which, if not corrected, will not end with wrecking your own happiness merely. You are doing positive injury, not only to yourself, but to the other members of your family.... You have ... let your highly wrought imagination control reason.... Had you no power over your feelings, this would not be sin; but it will not answer thus to yield to the enemy. Your will needs to be sanctified and subdued instead of being arrayed in opposition to that of God....
Man has been placed in a world of sorrow, care, and perplexity. He is placed here to be tested and proved, as were Adam and Eve, that he may develop a right character and bring harmony out of discord and confusion. There is much for us to do that is essential.... And there is much for us to enjoy. Through Christ we are brought into connection with God. His mercies place us under continual obligation; feeling unworthy of His favors, we are to appreciate even the least of them.2Testimonies for the Church 5:310-311. Mar 222
A life in Christ is a life of restfulness. There may be no ecstasy of feeling, but there should be an abiding, peaceful trust. Your hope is not in yourself; it is in Christ. Your weakness is united to His strength, your ignorance to His wisdom, your frailty to His enduring might. So you are not to look to yourself, not to let the mind dwell upon self, but look to Christ. Let the mind dwell upon His love, upon the beauty, the perfection, of His character. Christ in His self-denial, Christ in His humiliation, Christ in His purity and holiness, Christ in His matchless love—this is the subject for the soul's contemplation. It is by loving Him, copying Him, depending wholly upon Him, that you are to be transformed into His likeness. SC 70
Not boasting of things
without our measure, that is, of other men's labours; but having hope,
when your faith is increased, that we shall be enlarged by you. 2
Corinthians 10:15. KJV
