Nature is orderly. Nature operates by cause and effect. The laws of nature are always obeyed. Nature is all there is. God is Creator and Sustainer.
Laws of nature are descriptive , i.e., they describe what normally happens.
They are generalizations of what we observe. Exceptions cannot be ruled out. For the Christian, the laws of nature tell us how God normally does things, but they do not rule out the possibility that He could do things differently at times. It is a way of asking questions about nature . Theories are tested experimentally.
