“sustaining” does not explain innumerable miracles, answering our prayers, minimising suffering and preventing disasters, notably the extinction of all life on this planet.
To sustain implies continuous creation because without God nothing would exist nor continue to exist. It does not explain how or why miracles occur or any other form of divine intervention which suspends the laws of nature.
God is not surprised because He knows the blind laws of nature cannot cater for every contingency in an immensely complex process lasting billions of years which affects countless individuals. A universe that can produce perfect results **by itself **
is a fantasy.I don’t acknowledge that there are such things as “blind laws” as you say. The laws of physics are abstractions on the way that matter tends to behave. The law of gravity is not what causes something to fall to the ground anymore than the Pythagorean theorem is what causes right triangles to behave according to c^2 = a^2 + b^2. The form of mass entails that it is attracted to other forms of mass in a process known by humans as “gravity”. What would unify all these laws of physics, because there are distinctions between them? Ultimately you get to God who is the first source and final end of everything.
The laws of nature are descriptions of the orderly activity of physical objects which do not know or understand what they are doing. God does not will every drop of rain, as Calvin believed, nor is He
directly responsible for every event. To a certain extent the universe is independent and out of control because God foresees and permits accidents and disasters but He does not command them to occur.
Miracles are phenomena that do not fit into our limited understanding of the universe, but nothing is “miraculous” from God’s perspective.
That is because He uses His power to suspend the laws of nature for a specific reason.
The disparaging term “tinker” begs the question because it implies that the universe is a machine which can function successfully with any need for intervention at any stage of development from start to finish in spite of all the evidence to the contrary in the form of natural disasters, diseases and deformities.
Code:
I'm not sure what else I am supposed to say. I'm not allowed to use the word "machine" or "tinker" but then the replies to my posts suggest that the world operates according to blind laws and God fine tunes the universe. That's not the classical God of Aquinas (which was the whole point of starting this string of posts). I'm not going to say that understanding God in that way is useless, as long as it isn't the stopping point. Aquinas' understanding of God is probably about as far as one can get with unaided reason. Any further understanding would need to be given by a private revelation. The final stopping point is the Beatific Vision.
The universe is certainly a machine and Aquinas pointed out that “the order of nature requires that some things can, and sometimes do, fail”. (I, 49,2) This implies that God intervenes to a certain extent to control the course of events and ensure that development fulfils the purposes for which it is intended. Survival value alone is an inadequate explanation because it does not account for the urge to survive nor the increase in complexity of living organisms. There also has to be supervision and intervention at critical stages of the process rather rely entirely on a haphazard sequence of events - as if chance alone guarantees success. The overwhelming odds against survival in a hostile universe is sufficient evidence that our existence is not fortuitous but the result of Design and Providence.
