Libertarian free will and intercessory prayer

Justin Taylor's blog has an interesting post on (roughly) the oddness of intercessory prayer given (libertarian) free will. I'll give a brief response here, since I don't want to hog up too much comment space over there (and since there are already a couple of free will theists there offering good insights). A couple of preliminary remarks are in order:

First of all, though I can't claim to speak for every free will theists everywhere, I certainly think most of them would agree that libertarian free will (LFW) isn't necessarily valuable in and of itself. Rather, it is the necessary prerequisite for something else (genuine love, or something of the sort)--this is why people like Greg Boyd can argue that there will be no LFW after the consummation of the Kingdom (LFW as a tool to character-formation will have become obsolete). All this to say, LFW isn't something holy which must never be violated or anything like that (though I would argue that talk of God 'overriding free will' is linguistically awkward given my second point below).
Second, and this is perhaps more of a minority viewpoint within the free will camp (though I don't think it should be), I personally don't think it's helpful to speak of LFW as something which people 'have' (as if it were an merely accidental feature of human beings). Rather, something like LFW is entailed by the sheer fact of human existence. We are (among other things of course) centers of consciousness, others, both to our fellow humans and to God. Our very existence assumes a certain level of autonomy (within predetermined boundaries, of course). We are by our very nature agents capable of choosing between alternatives.

This having been said, what can way put forward by way of reply to Feinberg's take on the Arminian's prayer paradox? Well quite simply, I don't think Christians who pray for someone to have a change of heart want God to coerce this change. Theirs is an appeal to God's creativity rather than an appeal to God's power. If I pray for Bob to have a change of heart, I don't want God to 'possess' him and make him merely behave in a certain way (though at times that might seem like a nice thing). Rather, I want Bob to have a change of heart, and God to do whatever can be done to facilitate this change (with the full realization that this may not happen). Notice that this is also an appeal to God's omniscience since we (as limited humans) don't know what it would take (or if it's even possible) for Bob to become kinder or gentler (but God does).

Any questions?
