Genesis 2:7  This is such an exciting verse.  We learn of God's intent for man.  He formed him into a miraculous piece of work and then..."And the Lord God formed man of the dust of the ground, and breathed into his nostrils the breath of life; and man became a living soul."  This is the most important piece of information in the book of Genesis.  God's intent was that the human creation that he had formed would hold "Himself".  His breath.  The essence of God.

We are the tabernacle of the Holy Spirit of God.  This is what puts us in another completely different category from all the rest of God's creation.  We are living souls.  We can hold God's breath in a place within our being.  A place that--when empty--makes us hollow.  Makes us yearn.  Makes us miserable until it is filled with God.

Adam was flesh, then filled.  The second Adam--Christ--was first God, then wrapped in flesh.  We see in 1 Corinthians 15:45 "And so it is written, The first man Adam was made a living soul;  the last Adam was made a quickening spirit."

God's plan was to fill us with Himself.
