Danus,
If we had no free will because God chose us, then no one would ever be able to give up their faith. We know that some do, because some are even here on this board! And if you say that God didn't choose them to begin with, then they would never have come to the Lord to begin with. That based on your assumption that man only has the will to sin.
Edward, in theses post, and in keeping with the OP, we are discussing Free Will. Specifically man's free will. My response will be limited to that since we don't want to digress into other issues like loosing faith and such. Although those are good topics to argue as well, and could be in line with the OP, But I'm not sure because of your opening statement. "If we had no free will........."
No one, certainly not me, is saying man does not have free will. So that I am clear on this let me say that I believe man does have free will. I am saying man has free will. The will of man is free. However, what's being presented is, to what value, or involvement, is man's FREE WILL to his salvation, or to a lesser means does, or can, man use Free Will to actively choose God with only his free will.
If you've read what I've posted so far, and also look back at user "thisnumbersdisconected" last sentence that I said I liked so much; he states; "The co-existence of God's sovereignty and man's free will cannot be denied, though man's will must become conformed to God's will in order to follow, or come." This follows my point entirely.
1. Man has free will.
2. Man's free will is worthless in choosing God, because man's free will must conform to God's will. Why? because man's Free Will is sinful, and that's why it must conform to God's will which is righteous.
So in summing up your point, I have to ignore the first part since I am not stating that man does not have free will. I'm saying he does. As for man's will conforming to God's, if mans will is sinful than it must first be affected by something else to then conform to something else.
As for what we do know, well, we do know that people reject God. We do know that. If they reject God and have a free will, then they do so freely. However, we can not say that people who say they choose God, freely by their own will do so because we have already said that even their will must be conformed to Gods will.
The good news is, knowing or understanding this topic from a theological point of view, is not necessary, required, and nor is it a prerequisite in any way to salvation. Karl Barth has been on my mind lately because of another thread, and I've been reminded of some of his quotes. Two stand out; "In the Church of Jesus Christ there can and should be no non-theologians." - Karl Barth......... The other is....... "No one can be saved - in virtue of what he can do. Everyone can be saved - in virtue of what God can do."
