Christian Science heals. These three words ring like a joyful peal of bells on the ears of the sick and depressed, bringing hope and comfort. They are true, and because they are true they ring out with conviction. Christian Science heals because it recognizes God's creation as the only real creation, perfect, spiritual, whole, and indestructible; and because this creation is perfect already, there is no imperfection in it to require healing. And this is a fact, even when we seem to be going through an experience which tests our faith in the truth.
We can always choose whether we shall make the wrong use of a testing time and accept the condemnation of mortal mind, or whether we shall accept God's guidance and care, which lead step by step out of the temporary and into the eternal, bringing reassurance and regeneration all the way.
Mary Baker Eddy writes in "Science and Health with Key to the Scriptures" (p. 66), "Trials are proofs of God's care." To a sick or weary mortal there is always a trial of some sort, something to be healed, and that something is the fundamental belief that he is a mortal, subject to imperfection of all kinds. He tries so hard sometimes to remove what to him is a mountain, and the mountain appears to be all the more formidable, for a mental mountain can be removed only through faith in the ever-operative law of divine Principle.
