In my studies and writings I have relied significantly upon the work of William A. Dembski. I am sharing his comments that consider how God, who is immaterial and Spirit, interacts with the material world, including the human brain. Quantum mechanics gives nondeterminism to the universe which characterizes it as being informationally open and accommodating free will. Here is Dembski’s informative quote taken from my book, The Boundless Love of God: A Holy Spirit Story:
“. . . such [an open] universe will produce . . . patterns of events that stand out against the backdrop of randomness. . . . Such patterns [intended by God] could reasonably be interpreted as constituting novel information inputted from outside the system . . . in a nondeterministic universe, diving action could impart information into matter [e.g. a neural synaptic network] without violating any physical laws by which matter operates . . . A deity capable of co-opting randomness would impart information by arranging outcomes [with small probabilities and specification], but do so by channeling the material energy [e.g. of quantum tunneling in synaptic transmission] in ways that violate no principle governing matter. If divine action takes this form, the problem of finding the missing material energy by which God introduces novel information into the world simply does not arise. . . . information is then being transferred without any transfer of material energy. . . . Quantum mechanics . . . offers such a picture of the universe, allowing God free play at the quantum level. . . . In a world of irreducibly chance or random events [integral to the neural synapse], as some interpretations of quantum theory allow, [the Mind of] God can channel such events [and communications] toward preordained ends.”
Since the mind of Man is created in the image of the Mind of God, the postulate that Dembski shares reasonably applies to the immaterial mind of Man which can also channel communications of encoded information toward preordained ends with meaning and purpose.
