Jesus said to Philip (John 14:11), "Believe me that I am in the Father, and the Father in me: or else believe me for the very works' sake."
In the study of any natural science both deductive and inductive methods of reasoning are used. In Christian Science we use the deductive method when we start with God as the fundamental Principle or cause, and then view everything as derived from this cause, dependent upon it for being, and hence in perfect harmony with it. This primal and only cause or creator produces all, and man and the universe must therefore be spiritual, perfect, and eternal—in all respects like Spirit or God.
On the other hand, inductive reasoning is based upon individual experience. From one or more experiences we may perceive the working of divine law and realize that there is a governing Principle which is all-powerful and all-loving. The beginner in Christian Science may theoretically accept God as infinite divine Love, but when he experiences with unmistakable certainty the healing power of Truth, then he perceives by induction that there is a beneficent God.
