Laws of nature have no physical properties of mass /energy. They are platonic truths in transcendent realm that create & govern the Universe.
A common mistake we make is that we look for God in places where we ourselves wish to find him, yet even in the physical reality this is a complete failure. For example, if you lost your car keys, you would not search where you want to search, you would search where you must in order to find them.
For God to prove himself on demand, physically, would be a grave disappointment, and the strongest Christians should be considerably grateful that he chooses not to do so. The skeptic endlessly demands proof, yet God refuses to insult the true intelligence of man, the '6th sense', the chief quality, the acumen which distinguishes man from the rest of creation, faith.
