If freewill is doing what you want to do vs doing what God wants you to do does that mean acting on your freewill instead of acting according to God's will a sin?
Freewill decisions do not mean "doing what you want to do vs doing what God wants you to do"
If that were the case, it would mean that Jesus, and the myriad of other spirit sons, do not have free will, because they chose to do what God wants.
So, having free will, is not a sin.
Sin, is to miss the mark of God's righteous standards.
Adam and Eve made the freewill choice to eat the fruit that God told them not to which allowed sin to enter the world.
If they had never acted with freewill there would be no sin.
If you want to act according to God's rules you no longer have the freedom to act according to your own will.
If they were designed to only obey God - that is programmed, rather than made free moral agents, yes, there would be no sin... of course.
I think, you meant to say, "If you do not want to act according to God's rules...".
You do have the freedom to act.
God gives you that freedom.
It's like when we are given freedom to drive on the road, we must drive o the lanes designated, or on the side of the road permitted.
We have freedom, but there are limits to what we are allowed to do, with our freedom.
We are free to go to space, but make sure and don't take your helmet off, while up there.
There are consequences.
Are the wages of freewill death?
No. As I mentioned earlier, that would mean every intelligent creation of God sinned, but that is not what sin is.
Sin is disobedience to God.
That seems to be how it worked in the case of Adam and Eve.
No. Their freewill choice, going against God's standards, was sin... which is a consequence.
To illustrate.
A person being given a privilege of responsibility in a powerful king's house, is not given a death penalty.
If he commits adultery with the king's wife, and is put to death, death is a consequence of his action.
Similarly, sin and death, is a consequence of misusing one's free will.
The apostle Peter, uses a similar explanation.
1 Peter 2:16 For you are free, yet you are God’s slaves, so don’t use your freedom as an excuse to do evil.
