"IS there a God?" Because one is conscious of his own existence, he must admit that there is a cause of his being. And the fact that he is conscious of being points to Mind as the source of his existence.
Isaiah declares (45:11, 12): "Thus saith the Lord, the Holy One of Israel, and his Maker, Ask me of things to come concerning my sons, and concerning the work of my hands command ye me. I have made the earth, and created man upon it: I, even my hands, have stretched out the heavens, and all their host have I commanded." In accordance with Scriptural teaching, Christian Science declares that God exists as cause and man as effect; that God is the Mind of man and man is the reflection of divine Mind; that God, man's Father-Mother, is Spirit, and man, God's expression, is spiritual.
These are incontrovertible spiritual facts that have great value when applied to the human individual we are in the habit of calling man. They do something for him that is more far-reaching than he can at first imagine; they awaken him to the fact that, even though the human sense of himself seems of great importance, it does not do him justice. Satisfaction with a limited, imperfect sense of what his individuality really is keeps him from knowing himself as God's own image and likeness and from living here and now the Life which is God.
