God breathed Himself into Adam the day He made him. He was a lifeless shell until God breathed Himself into him. They were one, just like Jesus was One with Him.
And now we are one with Him, born of Him, filled with Him! Restored to Adam's place of authority and dominion, One Spirit with the Lord. [1 Corinthians 6:17]
As Adam walked with God, so we can walk with Him because we are one with Him. We have this treasure in these earthen vessels, so that the surpassing greatness of the power will be of God and not from ourselves. [2 Corinthians 2:7]
Hallelujah!
