In Christian theology, "nature" is simply the faithful rule of God over everything in the creation.
There are many alternative non-Christian conceptions of nature:
How should we understand the relationship of God to nature?
Robert Boyle, an important physicist and chemist, wrote a critical appraisal of nature after over 20 years of reflection on the matter. Boyle wrote from the remarkably Biblical perspective of 17th century Puritan England:
"Nature is a licentious word, and one which is detrimental to a fully based faith in the Creator.... Aristotle, by introducing the opinion of the eternity of the world, did ... openly deny God the production of the world. So, by ascribing the admirable works of God to what he calls "Nature", he tacitly denies him the moral government of the world."
--Robert Boyle, A Free Enquiry into the Vulgarly Received Notion of Nature, made in an Essay, London, the Royal Society, 1682. (New edition 1996 by E.B. Davis & M. Hunter, Cambridge U. Press).
Boyle had several other objections to the concept of "Nature": like "Fortune" or "Fate", Nature" or "Mother Nature" is a loose and vague notion. The concept is not found in the Old Testament. Instead, there are warnings against the deification of created things (see Job 31:26-27, Deut. 4:19, Rom. 1).
"The Christian is advised rather to pay admiration and praise directly to God Himself, who is the true and only Creator of the sun, moon, earth and those other creatures that men are wont to call the works of Nature."
Boyle, p. 134, quoted in James Houston, I Believe in the Creator, p. 36).
