Yelsew, i will agree with Archangel in this matter. the point is, where there is no law, there is no sin. come the age of perfection the only law to be obeyed was the forbidance of the eating of the fruit. with regards to Cain killing Abel, he was not given the punishment that was to be given come the Mosaic Law, for indeed, no such law existed then.
but to get closer to the issue now, we should ask, what was the law for?
well, there are at least 2 ways of seeing it:
first, in the point of view of divine establishment. God gas given Israel the Mosaic law so that, as a nation, they would live it with prosperity! the more the nation Israel obeys the law, the more it prospers and vice versa.
second, we can look at it within the spiritual context. in this light the law was not given for man to have a chance to get saved, nor to prove to himself that he is worthy of God's acceptance. the law, on the contrary, was given to show man that he is condemned! with that, anyone who realizes his unworthiness in the sight of God turns to find a chance to be saved with one thing that is left that he hopes to be existing - grace! this is why in Apostle Paul's letter to the Galatians he coined the law as the schoolmaster, one which will lead us to a realization, which is that we are unacceptable in God's sight.
but let me push the issue a bit more. our first disobedience to the law did not get us condemned or spiritually dead! it is the imputed sin of Adam! as i've written in another topic, with Adam, the nature to sin was passed to each man. with God, each man was imputed Adam's sin, making each one unacceptable to God. this is one undenialbe truth - that God in His sovereignty chose to get us condemned in His sight through the imputation of the sin of Adam. he did not ask for permission, he did not wait for man to be conscious, but He did it, and it was something He did for a cause, a product of His love to man!
this is what i want to ask Calvinists. what was God's purpose in doing the first thing to get everyone condemned? God also did it fot the non-elect. you see, God imputed Adam's sin to a non-elect that got them depraved. and the way you see depravity, man will not respond to God for being dead. but God did the first move in getting the non-elect into their situation of depravity. that means the non-elect was never given the chance by God to have the ability. but then Calvinists would say God gave them a general call when in fact God caused their inability to respond to such call.
to the Calvinists, in light of how you see man's depravity, what was God's purpose in imputing Adam's sin to everyone that got them condemned?
for, in the way i approached you, it would seem to lead to double predestination. but i doubt you cling to that. thus, you are to clarify this matter.
