Actual (non Neo)Calvinists deny the possibility of anything like free will because it reduces the power of God which is total. Now don't tar me with this view- I am no Clavinist. My sister-in-law is an OP Presbyterian and I discuss this from time to time with her preacher. The discussions are amicable and we both see them as sharpening our own respective reasoning.
I think you have no idea what you just started. :>)
