Jesus Christ taught that God is Spirit (John 4:24). Christian Science explains that God is all, therefore, the real substance of the universe is Spirit, not matter.
Many people try to understand the universe through the evidence the material senses present. They study the body to find health and the economy to find wealth. But there is more to health than can be found in the flesh, and more to wealth than money in the bank. As Jesus proved, health and wealth are spiritual, gifts from God, and originate in Spirit.
Trying to understand God’s universe through material sense is like looking through a straw to see around you. The view is constricted. To see reality, dispense with the straw—with the material sense of things—and use your spiritual sense. Then you’ll find abundance where you thought there was lack and you’ll find health where you thought there was illness. Your mental eyes will open to the infinite goodness of God, here and now, and the limited view of material sense will not limit you any more.
