In one of the greatest definitions of simplicity, Stephen Charnock stresses this very point: “God is the most simple being; for that which is first in nature, having nothing beyond it, cannot by any means be thought to be compounded.” Charnock then tells us why: “For whatsoever is so, depends upon the parts whereof it is compounded, and so is not the first being.” But remember, the being of God is “infinitely simple, hath nothing in himself which is not himself, and therefore cannot will any change in himself, he being his own essence and existence.”
