As such, nature derives its essence and substance from God, not vice-versa.
A clarification please. The alchemists (and other men of knowledge from antiquity) referred to an underlying material (materia prima/first matter) as the underlying canvas all variations possible are built upon. Are you suggesting God created this canvas )first matter), or as the Kabalists suggest, IS the canvas?
Excellent question.
The theological term is ex nihilo. God created everything out of nothing. He's the only one who can.
