All of us die the first death because of Adam and Eve. This is different to the second death to which we are lost. Where does it say in the scriptures there was no law to sin against? God's people have always had Gods law through the spoken Word of God before the written Word of God was given in Exodus 20. (see Genesis 26:5). The scriptures do not teach that we are held accountable for the sins of other people.
The scriptures we are discussing are in regards to inheritance of sin by having a sinful nature not being accountable for someone else's sins.
Ezekiel 18:2-4, [2] What mean you, that you use this proverb concerning the land of Israel, saying, The fathers have eaten sour grapes, and the children's teeth are set on edge? [3], As I live, said the Lord GOD, you shall not have occasion any more to use this proverb in Israel. [4], Behold, all souls are mine; as the soul of the father, so also the soul of the son is mine: the soul that sins, it shall die.
James 4:17, To him that knows to do good and does not do it to him it is sin.
Acts of the Apostles 17:30-31 [30] And times of this ignorance God winked at; but now (when a knowledge of the truth is come) commands all men every where to repent: [31], Because he has appointed a day, in the which he will judge the world in righteousness by that man whom he has ordained; whereof he has given assurance to all men, in that he has raised him from the dead.
It is because we are born with a sinful nature that we sin (Romans 5:12-14; Romans 5:18; Romans 7:1-25) We inherit Adams sinful nature and it is because of sin that we do that we stand guilty before God in condemnation which is why we need to be born again according to Jesus *John 3:3-7 because those who are born again do not practice known unrepentant sin according to *1 John 3:6-9
According to the scriptures we are not accountable for sin until we know it is sin (scriptures posted above). Is there any reason your not answering my questions?
