That certainly doesn't follow. Opening of a door is a consequence of my turning the doorknob which was my intention in turning the knob in the first place. God intended the results of the fall he engineered. Thus, no reason to be surprised by man's physical corrpution.
I understand your disagreement with the reformed perspective and I am not engaging that debate here. We can disagree on that point and still be friends and fellow witnesses for Christ.
Agreed. :-)
