A Reverse Proof for contingent freedom

I’ve been wrestling with this idea.

1. God is the only absolute, necessary being (all confessional Christians agree to this).
2. That which is not absolute is contingent.
3. Human choices are not absolute, thus contingent (2).
4. There is both necessity and contingency (1, 3).

Is that the same thing as “free will?”  It is probably not the same thing as libertarian free will, nor have I covered all of the finer points.  I think the propositions stand, though.  All of this is another way to affirm the necessity of consequence and the necessity of the consequent thing.
