In the Sermon on the Mount, Christ Jesus taught the great lesson that supply comes from God, not from matter or human sources. He explained that even the birds are fed and the flowers and grass clothed by the heavenly Father; and then he asked (Matt. 6:26), "Are ye not much better than they?" But there was one stipulation that he included in his discourse: "Seek ye first the kingdom of God, and his righteousness; and all these things shall be added unto you." This sequence involves a rule which makes abundance a natural experience.
According to the revelation of Christian Science the kingdom of God is the only realm, and there man exists as Mind's spiritual idea, infinitely supplied with all truth and goodness. The realm of the physical senses, where limitation is experienced, is a false mental state, a temporal dream, from which mankind needs to be awakened. Mary Baker Eddy says in "The First Church of Christ, Scientist, and Miscellany" (p. 5), "Wholly apart from this mortal dream, this illusion and delusion of sense, Christian Science comes to reveal man as God's image, His idea, coexistent with Him—God giving all and man having all that God gives."
Looking directly to God for supply, we bring His law of infinite giving to bear upon human problems of lack. Christian Science demonstrates this law of God, His changeless will, through which He acts to provide His children with all that makes for spiritual freedom. It is through divine law that man's completeness is manifested. For this reason it is in terms of law, rather than in terms of matter, that we should consider supply. Because Love's will is invariable in its action, there is no interruption of the flow of good from God to man, no fluctuation in its infinite quantity, no deterioration of its infinite quality.
