He has set up a boundary condition for us, however, which He honors as well. Christ, the prophets, the apostles, and the body of believers. Outside of miracles performed for such a purpose, we can depend upon laws of physics to be in operation and totally predictable all the time. God did not give us an 'Alice in Wonderland' world that would keep us in continual disarray. We can live without consternation in a predictable habitat, and not have to worry on a minute by minute basis what some unpredictable, capricious deity has in store for us.
Miracles are still possible.
In fact, miracles are part of our belief structure, if we trust the Bible, and put our faith in God. Miracles are just not part of the scientific process. Neither are miracles the only point of departure between the opposing realms of science and religion. Science explains, religion reveals, science informs, but religion reforms. Science involves careful observations, natural explanations, rational inferences, and deductive reasoning.
