Must be Born Again from Above

John 3:3-8 
3 Jesus answered and said to him, “Most assuredly, I say to you, unless one is born again, he cannot see the kingdom of God.” 4 Nicodemus said to Him, “How can a man be born when he is old? Can he enter a second time into his mother's womb and be born?” 5 Jesus answered, “Most assuredly, I say to you, unless one is born of water and the Spirit, he cannot enter the kingdom of God. 6 That which is born of the flesh is flesh, and that which is born of the Spirit is spirit. 7 Do not marvel that I said to you, ‘You must be born again.’ 8 The wind blows where it wishes, and you hear the sound of it, but cannot tell where it comes from and where it goes. So is everyone who is born of the Spirit.”

One must be made into a new creation to move from sinful mortality to God's sinless presence in immortality.  Only God's breath, His Spirit that first breathed life into the clay of Adam, can blow into us to transform our spirit.  So He moves as the breath of a blowing wind to change us in an unseen new birth.  This is God's work which man cannot duplicate, imitate, nor even fully investigate; so we can only see the results of being reborn.
