My thread agrees with you here and it does not challenge our autonomy concerning our choices, which is God-given, for this is what incurs accountability. The overall concept in this thread to me is the fact that since God foreknew their choices, it which makes what they did part of His plans, which He already established prior to creating.
May our correspondence concerning this or any issue be out of brotherly-love and for truth's sake, which otherwise would prove vain. Agreed?
No it does not agree with your thread. Let me again try to explain the difference. You said, "Their disobedience was evidence of possessing a sin nature prior to the act."
Let me explain my original response to that a little simpler and at the risk of repeating myself.
Having a sin nature means that sin was inherent within Adam to begin with. The word inherent means 'built-in, inbuilt, integral'. Therefore saying that it was inherent is to say that God created that which is evil (that sin was built-into Adam) and not to have created Adam as "very good".
