“Great art is the outward expression of an inner life in the artist, and this inner life will result in his personal vision of the world.” - Edward Hopper.
In Menoras Hameor R. Yitzchak Abuhav explains: “Blessed is He Who spoke and the world came to be” - speech was the means by which the Holy One brought the heavens and the earth into being, as is written in Tehillim 33:9 “For He said and it came to be”. Our Sages teach (Bereshit Rabbah 44:22): “The word of the Holy One is actual deed (i.e. the actualization of it; making actual or really existent; it’s an act of coming into existence)”.
So when G-d spoke, through His words He brought the universe into being. (What He speaks into existence comes into existence).
But why did G-d choose to speak creation into existence? Why did G-d choose to ‘express Himself’ in this way; use speech as His instrument to create? (Why not create things in the way G-d created Adam).
