Sojourning Under the Sun: Perfection (Genesis 2)

The Lord has created and placed Adam in a wonderful garden sanctuary where Adam has a taste of heaven.  This is a place where man communes with the Lord and fellowships with the living God.  However, in the midst of this Garden there are two trees that will testify to man’s allegiance to the living God.  What is the significance of this garden?  Why does the Lord place these trees in the midst of the garden?  Why does the Lord enter his Sabbath rest after revealing the generations of the heavens and the earth?
