God gave Adam and Eve everything they needed in the Garden.
Gen 2:8-9
And the LORD God planted a garden eastward in Eden, and there He put the man whom He had formed. And out of the ground made the LORD God to grow every tree that is pleasant to the sight and good for food, the tree of life also in the midst of the garden, and the tree of knowledge of good and evil.
Notice that even the Tree of Life was available for them among the variety of other trees that were good to eat from.
Gen 2:15-17
And the LORD God took the man and put him into the Garden of Eden to dress it and to keep it. And the LORD God commanded the man, saying, “Of every tree of the garden thou mayest freely eat; but of the tree of the knowledge of good and evil, thou shalt not eat of it. For in the day that thou eatest thereof, thou shalt surely die.”
Next, notice that all satan had to do was to get their attention off of everything else that God had provided them and on to the one thing they didn’t have.
Gen 3:1-7
Now the serpent was more subtle than any beast of the field which the LORD God had made. And he said unto the woman, “Yea, hath God said, `Ye shall not eat of every tree of the garden’?” And the woman said unto the serpent, “We may eat of the fruit of the trees of the garden, but of the fruit of the tree which is in the midst of the garden, God hath said, `Ye shall not eat of it, neither shall ye touch it,lest ye die.'” And the serpent said unto the woman, “Ye shall not surely die; for God doth know that in the day ye eat thereof, then your eyes shall be opened, and ye shall be as gods, knowing good and evil.”
And when the woman saw that the tree was good for food, and that it was pleasant to the eyes, and a tree to be desired to make one wise, she took of the fruit thereof and ate, and gave also unto her husband with her; and he ate. And the eyes of them both were opened, and they knew that they were naked; and they sewed fig leaves
together, and made themselves things to gird about.
Adam and Eve had a perfect environment, a perfect relationship, and all of their physical, soulish, and spiritual needs met. I believe that since He is the same yesterday, today, and forever that they could even ask any questions of Him that they wanted during their cool of the evening walks and He would gladly share His wisdom.
James 1:5
If any of you lack wisdom, let him ask of God, who giveth to all men liberally and upbraideth not, and it shall be given him.
Yet instead of focusing on and being grateful for everything they had that God had freely and liberally given them, they got focused on the one thing they didn’t have, and ended up loosing everthing.
