I could have chosen yesterday not to eat it, but I cannot, having eaten and digested it, choose not to be affected by the calories. If I bring my cheesecake home from the restaurant with the intent to eat it before bed, even one of my dogs could thwart my free will by being unusually naughty while my back is turned. (However the fear of ME nearly always prevents that sort of mishap. )
Honestly, Paidion, we do not disagree on this. You maybe think my examples have nothing to do with freedom of will, but that’s just the way we’re choosing, as individuals, to think about this. Father is making us freer day by day by the work of Christ. How can the Son set us free if we have never been slaves to anyone or anything? He is SETTING us free, and in that sense you could use an already/not yet argument – but there it is; the “not yet.” Which says to me that we are not natively endowed with libertarian free will. We may achieve that at some point, or perhaps we’ll go on growing in it through the ages of the ages; I suspect the latter.
