God's Working in Birth

Ecclesiastes 11:5   
As you do not know what is the way of the wind, Or how the bones grow in the womb of her who is with child, So you do not know the works of God who makes everything.

   John 3:6-8.   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.”

   Genesis 2:7   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 being.

God works in the spiritual realm to give life; this shows some evidence in a changed life afterwards, but is not something you can see happening.  This is why Jesus tried to tell Nicodemus of His working to regenerate us - a new birth is by God's breath (spirit) into us, as in the creation of Adam.  We must never imagine we are in Christ based on our upbringing or what good things we do; only Christ dying in our place and grace given for us to believe that will ever allow God's breath to change us from death to life.
