The account of Adam and Eve takes place in the first scriptures of the Bible, Genesis. Satan in the form of a snake had come to Eve when she was observing the tree of knowledge, and it said to the woman: “Did God really say that you must not eat from every tree of the garden?” At this the woman said to the serpent: “We may eat of the fruit of the trees of the garden. But God has said about the fruit of the tree that is in the middle of the garden: ‘You must not eat from it, no, you must not touch it; otherwise you will die.’” At this the serpent said to the woman: “You certainly will not die. For God knows that in the very day you eat from it, your eyes will be opened and you will be like God, knowing good and bad.”
So we see here that Satan was calling God a liar, and selfish. That God was keeping something from Eve, something Good.
But we know that from reading this account, God was protecting them, he told them of the consequences and who's to say he wouldn't have rewarded them with the fruit of the tree at an appropriate time after passing the test? They had every single good tree of the garden to eat from, but they stole from the one they couldn't have. So it's understandable why they'd be punished and exiled from the garden. But the Bible offers hope for mankind, that soon they will regain the ability to live Forever in it and not suffer anymore, and never experience badness for the rest of their days.
Jesus came to earth and prophesied about the events to take place before then, the events to follow after and also his ultimate goal to die for us. A perfect beings life to cover Everyone's sins. Reading his life's ministry from Matthew to John ( the apostles accounts on what events they saw take place) helps us understand what We need to do in order to gain that hope, by following the model he set for us.
