Nicely done.
When I read this part: "Man has a will, but his will is not free." I heard in my head the two gruff voices of Gerstner and Sproul insisting that we have never made a choice that we didn't want to.
Unregenerate man has a will and freedom to do whatever he wants to under the category of actions that do not lead to righteousness - even feeding the hungry or giving to the poor counts for only his own self-righteousness and a puffed self-alignment to the moral, the greater good.
This is only to say I agree with you and to ask you (and anyone else that feels inclined to respond): does regenerate man pre-glorification have a mutable free will to a lesser degree than pre-Fall Adam or simply more options post-regeneration?
Thank you.
