This summer I have been preaching a series of sermons on the Canons of Dort, in recognition of the 400th anniversary of their publication. Yesterday I preached a sermon entitled Corruption and Conversion, I. I spent quite a bit of time exploring the nature of the human will from the perspective of Adam before The Fall, Adam after the Fall, The Experience of the Christian, and the Christian in the glorified state.
I cited two articles that were quite helpful in this discussion. Both refer to Augustine and draw upon Latin terms he used. Hopefully you will find these articles beneficial too.
