God created man in His image and breathed life into this man, which He called Adam. Adam dwelled in a heavenly garden know as Eden; with his help mate Eve. One day while in the Garden they partook of the tree of knowledge of good and evil and this caused them to become self-conscious.
By becoming self-conscious they essentially died to the Spirit and were banished from the garden. Death of the Spirit does not mean physical death, it is a reference made when an individual is separated from God’s Spirit. God does not commune with His children in a natural, physical way, but by the connection of His Spirit. God cannot commune with anything unholy and because of sin; Adam and Eve were now unholy. Since the deception of the serpent caused Adam and Eve to fall into sin, God would now curse the serpent and foretell of His plan to destroy the serpent so that He may once again commune with His children. God so loved His creation that He would now send His only son into the world to take the sin of the world upon Himself and be nailed to a cross for the sake of all God’s children. His blood would be shed and He would die, go to the grave and be resurrected for the salvation of mankind. Christ would rise and be seated at the right hand of the Father and whom so ever believed in Him would receive eternal life. Eternal life is connection to the heavenly Father by way of the Son, which was sent into the world so that believers could once again commune with the Father by way of His Holy Spirit.
