you would be wrong as you ignore the passage in the pentateuch that states that the children should not be punished for their parent's sin. God does not punish innocent people and it has nothing to do with 'man's view of human rights'.
when adam and eve sinned, there children did not do so unless they did the exact same act as adam did. PLUS you ignore the fact that children aren't mentioned till AFTER the expulsion
Sin comes from defiance.
God shows he is God by obeying his own rules.
The only reason Children of Adam will sin , is because they are a separate entity from God.
Sin= Death .
Sin cannot be taken away.
But Jesus payed the price for everyone by paying the parking ticket of sin , and dying for us.
He lived sinless , but died to pay our debts.
Jesus didn't have to die.
But he did , and went to hell , so we could live forever.
But God , being righteous as he is , gives us salvation even if we do not deserve it , only by believing in Jesus.
Imagine Death is community service , and hell is jail.
If we lived forever , we would have sinful nature forever.
Our eternal sinful nature causes us to go to jail.
We will do community service and will still have to go to jail.
Jesus is our lawyer.
Even though he gets us free from Jail , we still have to do community service , Death.
First of all Genisis, like all creation stories which are found in almost all religions, was an oral tradition that someone wrote down somewhere in antiquity. It was most likely was not written by Moses but we have no proof of that one way or the other. No surviving copy of Genisis by the origional author exist.
As far as Cain's wife, we really cannot say for certain. If we are to accept by tradition that Adam and Eve were the only created persons and everyone was decended from them, than it is reasonable to believe that indeed Cain had to have married his sister. Thus they produced offspring by incest. Having said this it has been pointed out that incest was not at that time a sin. Well nor was murder? Cain seemed to be held liable for committing murder (his brother Able) yet no where prior to that was it spelled out in Genisis that murder was a sin. The point is that there are a lot of inconcistancies in Genisis and in the bible in general. Why would god create a world where he knew people would have to reproduce by means he felt was wrong (incest). Why would he indeed not create a supply of mates that could be available for Cain and his others relatives who were not related by blood? The fact is the book of Genisis is not a "inerant" work. It is not word for word divine from god's lips. It was written by a man who was trying to explain creation as it had been told to him.
Incest isn't a sin.
It's an abomination , as with eating unclean foods like pork.
It's not sinful , just very bad end results like deformities in incest and diseases from pork.
Adam and eve were probably very different in genetics , which let them have children who could interbreed without having deformities.
Murder was a sin , but incest wasn't considered an abomination of God because it produced something good at the time.
But around Moses's time , Incest would be harmful , thus would be considered an abomination , because of the effects it could have on children.
Abominations may be sinful , and may not be sinful.
Incest at the time of Adam was good, and was not sinful.
But as soon as it was bad for you , and you had knowledge of that , then it became sinful.
Homosexuality is an abomination.
It's not a sin , but it's sinful if it affects someone's faith or life in a negative way.
Same with pork.
Eating raw pork will cause you to sin if you actively know it's bad for you , but if you don't know if its bad for you or you cooked it , then it isn't sinful , because you know not the consequences or the harm it could cause.
In modern times , homosexuality makes people become atheists , so I would say it's a sinful act , because it affects negatively.
If a man has sex with a man , they have committed the sin of adultery.
But if a man dreams about being with a man in a homosexual way , they haven't committed a sin as long as they haven't done any physical or faith-based damage.
