“H ashem will order the blessing to be with you in your granaries…”
(Devarim 28:8)
The Gemara says (Bava Metzia 42a): A blessing will only rest upon something that’s not readily visible.
Why does Hashem only perform miracles on that which is hidden from the eye?
To understand we must recognize the prevalent misconception about the difference between nature and miracles. People assume that nature’s a system of cause and effect that Hashem established within creation. On rare occasions Hashem halts the natural process of the world and performs outright miracles.
