If we're faced with a difficult physical condition, we don't need to succumb to depression or fear. Nor need we ask in despair, "Why me?" Help is available when we turn wholly to God, Spirit. Physical disability and disease can be overcome by understanding that matter, the opposite of Spirit, is not true substance and has no real power.
God alone is the one true cause and power, and man is His perfect effect, His image. Man, then, can only reflect God's nature. God is Love, so man must be the image of Love. God is Spirit, so man must be spiritual as His reflection. He must be incorporeal, inorganic. Can your image in a mirror differ from you? So God's image, man, cannot change unless God changes. God cannot be sick or disabled; therefore man cannot be sick or disabled. God can never be less than God, good, and man can never be less than His perfect likeness.
That which appears as sickness or disease is mortal belief. It has no foundation in immortal Spirit. God does not share His power with anything unlike Himself. Through humbly accepting that God is the only power, and understanding that man is His likeness, we'll experience healing.
