You say that, but from my experience, most non-Calvinist go to the other extreme: Man is in control, as he makes the decision.
That would be an error in the other extreme. "God is omnipotent; He created man with free will" is I think the starting point. There is a great deal of possibility for paradox and veering one way or the other within this, but IMHO, it's ending up at one extreme or the other that lets you know you have built upon an error somewhere.
Thanks very much for your reply..
