Someone may ask, Could God not have simply overlooked Adam and Eve’s sin?
No, because that would have further undermined respect for his authority, perhaps encouraging future rebellions and resulting in even greater suffering. Ecclesiastes 8:11
In addition, condoning such disobedience would have made God a party to wrongdoing.
To be true to himself, God had to allow Adam and Eve to suffer the consequences of their disobedience.
As a test of their appreciation God gave them a simple command; they were not to eat of the fruit of a certain tree; and he warned them of the consequences if they did eat of it.
They were created perfect in mind and in body. They willfully and deliberately disobeyed.
They could neither plead ignorance, nor claim inherited imperfection and the tendency to sin.
So what basis was there for forgiving Adam and Eve’s sins? Absolutely none!
Eve and Adam confessed to their willful sin. They had no basis for asking for His forgiveness and they did not ask for it, for that would have meant for God to set aside his own law.
