But I think it works the other way around. Pretending for a moment that a cell is capable of reason (and it may be for all we know), if a cell tries to understand us by understanding itself and its own processes, it won't get very far. It must imagine beyond itself to even begin to encompass us.
Suppose it is a kidney cell and it can't figure out WHY we send it liquids that are harmful and in some cases poisonous to it, liduids that kill other kidney cells nearby. But, we need the medicine, even though it carries some immediate risk of kidney damage, to cope with some other medical condition that has greater risk of worse long-term damage to the overall system (our body).
It can't fully discern the purpose behind our choices because it doesn't know what we know. And it can't begin to gain any understanding by thinking from its own standpoint, it can't even start to imagine what sort of motive there might be to such an action if it limits its perspective to itself. But, ultimately, we are looking out for the best interests of our kidney, too.
Looked at from that standpoint, attempting to understand God by looking inward seems...inside-out.
You assume we exist within the molecules and networks within our nervous system. You do not actually know that.
