The Bible doesn't say how long "a long time" was, but okay so far.
Here's where your logic breaks down. His choice to sin (for he was not deceived as the woman was) IS the fall as far as you and I are concerned for we are all counted as in him, not in her. This, I suspect, prefigures the believer's positional standing in Christ, simultaneous with his positional removal from Adam.
OK so Adam chose wrong. Why make this sound like a switch clicked in the universe from "all righteous" to "all sinners"? There were only two people and they represented all humanity in that all humanity from that time on has been in the sinful camp.
But that is a far cry from blaming Adam for my sin. There is no connection.
I'm not going to argue the nature of Adam's nature. All I need to do is remind you that his relationship with God - heretofore perfect - was now damaged by his choice to sin. So it is with our own relationship with God, BY NATURE (take that as literal or as a figure of speech but it amounts to the same thing, for we ALL sin and fall short...where do we get that? From Adam).
No we don't. All we got from Adam were our genes, and a bad example, just like all of us pass on to our own offspring.
Dead wrong. The old man is all one has and is apart from Christ, and the old man, the flesh, IS sin.
How can the flesh of itself be sin? I have eaten some good flesh. Is that also sin? Adam was made mortal/flesh. By your logic, Adam was made sin, by God.
Dead wrong. The old man can do nothing BUT sin.
Not so. Adam, made of flesh, lived without sin for a while.
Every day, pagans love their children and do noble things, which are not sin. The problem is that even with one sin, and no Christ, the wages of sin is death. But please don't give be some story that my eyes can see is false.
That's why the only remedy to Him is the crucifixion...being reckoned as DEAD. The logic of your position, to the contrary, seems to be that the old man can be tamed, trained or reformed to an extent that eventually pleases God.
You do realise that "old man" is an analogy for our past self making sinful choices? It gets, by analogy, drowned at baptism.
Walking with Christ, we make better choices as the "new man".
But the "old man" rears its ugly head when someone cuts us off in traffic. It is only by analogy "dead". Our past bad habits come back to haunt us under pressure.
Dead wrong. The new man CANNOT sin.
Why do you think we pray "forgive us our trespasses as we..." if the new man CANNOT sin? Are you saying we CAN and DO sin, but God forgives this? But paleeese don't say you cannot sin.
We -- all of us -- get that alienation from Adam.
Again, not so. God had a fine relationship with Abel.
We -- all of us -- get that alienation from SINNING OURSELVES.
