The power of one’s mental focus: Ellen G. White, The Ministry of Healing

The power of one’s mental focus: Ellen G. White, The Ministry of Healing , p. 247:
We are in a world of suffering. Difficulty, trial, and sorrow await us all along the way to the heavenly home. But there are many who make life’s burdens doubly heavy by continually anticipating trouble. If they meet with adversity or disappointment they think that everything is going to ruin, that theirs is the hardest lot of all, that they are surely coming to want. Thus they bring wretchedness upon themselves and cast a shadow upon all around them. Life itself becomes a burden to them. But it need not be thus. It will cost a determined effort to change the current of their thought. But the change can be made. Their happiness, both for this life and for the life to come, depends upon their fixing their minds upon cheerful things. Let them look away from the dark picture, which is imaginary, to the benefits which God has strewn in their pathway, and beyond these to the unseen and eternal.

Ellen G. White, The Ministry of Healing, p. 246: “The power of the will…”

Ellen G. White, The Ministry of Healing, p. 246
The power of the will is not valued as it should be. Let the will be kept awake and rightly directed, and it will impart energy to the whole being and will be a wonderful aid in the maintenance of health. It is a power also in dealing with disease. Exercised in the right direction, it would control the imagination and be a potent means of resisting and overcoming disease of both mind and body. By the exercise of the will power in placing themselves in right relation to life, patients can do much to co-operate with the physician’s efforts for their recovery. There are thousands who can recover health if they will. The Lord does not want them to be sick. He desires them to be well and happy, and they should make up their minds to be well. Often invalids can resist disease simply by refusing to yield to ailments and settle down in a state of inactivity. Rising above their aches and pains, let them engage in useful employment suited to their strength. By such employment and the free use of air and sunlight, many an emaciated invalid might recover health and strength.
