People’s souls can incline so as to invite them, or reject them, in the face of the spirit of God.
I believe there is such a thing as an “eternal inclination” which makes such paradoxes as infallible predestination and genuine choice possible to coexist. The broad picture is painted on another plane, the eternal plane. In the plane of time, we have some leeway about details, yet never so as to surprise or get ahead of God.
That said, I'm not familiar with the concept of "eternal inclination" though with the certain exorcists and the Lutheran minister Dr. Kurt Koch who delivered thousands of people from occult bondage, I accept that certain people are chosen at a young age by the Brotherhood of Darkness for their sinister purposes.
