Neurological research seems to have concluded that free will does not exist. That everything is predetermined, and that a scan can determine what decisions you will take and what choices you will make.
I am somewhere in the middle on the free will versus determinism ideologies. As a believer in God’s sovereignty, I cannot believe in absolute free will, but as a believer in God’s mercy and justice, I cannot believe in absolute determinist. I believe in a sort of “free within constraints” model, which will obviously have some elements of determinism as well as a tinge of free will.
