In your opinion what causes christians to believe in Jesus

[Sheldon]

Free will of a limited kind is a profound contradiction in terms.  Limits are exactly what people skeptical of free will are talking about.  Limit being a damned good antonym for freedom in the first place.

Not really.  We have free will even if we only have two bad choices.  Freedom only extends our possible uses for our abilities to assess and choose.

Every restaurant menu, with its limits, would negate our ability to choose by your argument.

Exactly, I hate the term free will, as it can never be entirely free, certainly we perceive some autonomy of choice, the question is whether that autonomy ends, in the same place as our perception. Or if it is all allusion, but as another poster has already pointed out, determinism and fatalism carry a burden of proof, and seem for now to be unfalsifiable ideas. 

On a more amusing note, why would a fatalist or determinist bother trying to find out, if nothing they do will change the result.
