The stories in the Bible do not describe in detail how Adam and Eve taught their children.
No one could have taught their children better than God.....he educated his angelic sons long before humans were created.
He also educated Adam long before he created Eve, because he had to be the family head, responsible for the spiritual and physical well being of his wife and children.
It was because they both abused the free will that God gave them as a gift, and turned it into a curse. Every evil committed on this earth is an abuse of free will....someone forcing their will on others.
Even the devil was once an obedient son who fell into the trap of thinking he could be equal to God...if only he had lower creatures to worship him. He plotted a way to get the worship he wanted, by deception.
We also have a God-given conscience, designed to give us natural responses to certain actions that we know are wrong....so we can avoid bad consequences.....but we don’t always take notice of the small voice inside our heads.
But at least we know from the side, They let their children know that God exists. I don't know how Adam and Eve explained to their children that human will surely die.
I guess they all got that rude awakening when Cain killed his brother....inflamed by jealousy, Cain’s anger festered until he committed pre-meditated murder, which under God’s Law, like the laws of man, is not manslaughter, which can be committed in a flash of uncontrolled anger, or even accidentally.....this was a coldly planned taking of human life....pre-meditated murder.
Abel was the first human to die, but not from old age or sickness, which the rest of humanity had to suffer because of the now defective nature of man. Yet every way a human can die is unnatural for beings designed to live forever in mortal flesh. That is what “the tree of life” was for in the garden. (Gen 3:22-24) And why God determined not to allow access to that tree again in man’s now sinful state.
Since Adam and Eve did not obey God's word in the first place, we do not know what truth they learned from God. The Bible does not go into detail, because if It goes into detail about everything, the book will overwhelm me.
That is true....but there is enough in the Genesis account to get a fair idea.
One thing stood out....there was not a single word of remorse from any of them. Adam and his wife blamed someone else and Cain simply complained that the punishment he received was too severe.....since there was a shortage of humans on the earth, God banished him from his family. He was exiled away from them in a foreign land.
So we can't blame Adam and Eve for not raising their children, because there were two children. So things are hard to explain.
A child is good in the eyes of God, a child is not good in the eyes of God.
I guess the hardest part was explaining why they could no longer access the garden since all the delicious fruits would now be off limits to them.....God told Adam....
Gen 3:17-19....
....“Because you listened to your wife’s voice and ate from the tree concerning which I gave you this command, ‘You must not eat from it,’ cursed is the ground on your account. In pain you will eat its produce all the days of your life. 18 It will grow thorns and thistles for you, and you must eat the vegetation of the field. 19 In the sweat of your face you will eat bread until you return to the ground, for out of it you were taken. For dust you are and to dust you will return.”
What do you notice there..? The ground outside the garden to which they had been banished, was now “cursed”....nothing would grow abundantly anymore, and Adam and his wife were now forced to “eat bread” which requires growing the grain to obtain the flour.....but on cursed ground, the yield would have been meagre and of low quality. No more delicious fruit for the taking. They had to work hard to obtain even the staples.
In time their two sons were born and grew to adulthood.
Gen 4:2-5....
“Abel became a shepherd of the flock, but Cain became a cultivator of the ground. 3 After some time, Cain brought some fruits of the land as an offering to Jehovah. 4 But Abel brought some firstlings of his flock, including their fat. While Jehovah looked with favor on Abel and on his offering, 5 he did not look with any favor on Cain and on his offering. So Cain grew hot with anger and was dejected.”
How long it took to obtain the fruitage of the land is not stated, but we know it must have taken a lot of hard labor to grow it....and then to be told that his brother’s offering was superior....Cain lost the plot! God warned him that his anger would result in something bad, but he refused to be appeased. His anger festered into murder. This is the first mention of sacrifice to Jehovah....Adam and his wife are never said to have made any offering to God.
Were Adam and his wife responsible for raising their children correctly and teaching them about God and how they came to be living a life that didn’t feel right? Who else could they blame......they both disobeyed God but for different reasons.....both did so with selfish interests, just as satan did.
We can not take our existing accumulated knowledge and experience to compare the original things, this is unreasonable, to some extent, unfair, I mean in terms of knowledge.
We know that God is perfect and he does not make defective things.....it was the humans who disobeyed him and suffered the consequences of their own actions. Death only came as a result of sin.....if the humans had never sinned, they never would have died. That means that their bodies were designed in such a way that cell renewal was a constant process....a fact that science knows, but cannot explain why the process slows and eventually stops, ending in multi organ failure and death in old age. How many ways are there to die.....?....its countless!
Because the knowledge we gain is a situation that God leads and teaches through real examples, For example, parents have all kinds of problems with their children.
They do in a sinful state....but what if perfection had remained? Was there a guarantee that free will could not be used in a bad way? What caused the once perfect angel we now call satan the devil to deviate from his path...who can he blame for his sin? What does this tell us about all of God’s children who are gifted with free will? God is a perfect parent and yet he lost a third of his spirit sons to disobedience and defection from their place in heaven. And the majority of his earthly children are likewise condemned to death because they refuse his offer of salvation. (Matt 7:13-14; 21-23)
Even my own knowledge is built on all imperfections, with my own imperfections, imperfections from elsewhere, I wish I was in heaven, only to receive the perfect knowledge?
Sadly, imperfection is all we have ever known.....and we can learn to live well in spite of it by taking notice of what God and his son have taught us in the Bible.....but we also have to live in a world where the majority do not obey God and turn away from bad.....if we have no hope of things getting better, what is the point of this life?
If God cannot restore us back to the original perfection with which humans were created, then he is a failure.....and that is something God can never be. (Isa 55:11)
He has promised a return to our former sinless state and guaranteed it by the sacrifice of his son......a renewal of the earth itself is also promised, to repair the damage done by humans intent on greedily extracting as much from the earth as they can, without regard for why God put those things there in the first place.
Was oil put in the ground to be made into polluting substances with no regard for any bad health outcomes or in resulting earthquakes because the lubricating oil was removed from the tectonic plates?
Greedy humans have caused much damage to the earth and to human health.... this beautiful planet was never meant to host such evil people. So it’s good to know that God will restore everything back to the way is should be.....with lessons learned and a guarantee that it can never happen again.
Can I ask you why you believe that God is going to take humans to heaven when it was never in his original purpose to do so..?
What is the kingdom of God.....and what is its purpose in the future?
We have to know the answers to those questions because each one is fundamental to where the human race is going to spend eternity.
