A tad more on the last analogy. . . . Regarding the difference of soul/self-consciousness in a human versus a machine. You might say, hey, that's a big difference! And it is . . . in terms of awareness. This is where I suggest we are but witnesses--individual points of awareness of God's glory. But unless you are a pantheist (believing we ARE God at the core) then it is admitted our awareness is limited. Now, we may be aware of a near limitless amount of possibilities, options etc., within the scope of our choices (of thought, action) such that it SEEMS like we are utterly "free" to choose anything without limit. . . . Nevertheless, we are still limited to ONLY the parameters of the nature God has set for us. We cannot go outside that.
Thus, we do NOT have unfettered "free will". If we did, it would mean there something outside of God's control which puts us BEYOND God. Hence the temptation for some (ie., the unregenerate) to want to see things this way. For, at base, our whole problem as the devil first prompted it . . . is in wanting to be gods ourselves; to be our own sovereigns. . . .
And, just like the computer mentioned, which seemed like a self-willed human, because it had within its design a near limitless amount of possible designer-programmed responses to changing situations, we too SEEM like we have "free will", independent of our Designer.
In all this, I am most fascinated by what is it in someone--what is that impulse, that desire, that inclination . . . which rejects this line of thought . . . wanting to see it that God's sovereign will is best shown in His relinquishing His sovereignty to glorify creatures' "free will" . . . vs. the one who wants (or just does) to see it that God's will is absolutely sovereign and the creature is wholly at His mercy and grace?
