Genesis 1: 27 - 28: So God created man in his own image, in the image of God created he him; male and female created he them. And God blessed them, and God said unto them, Be fruitful, and multiply, and replenish the earth, and subdue it: and have dominion over the fish of the sea, and over the fowl of the air, and over every living thing that moveth upon the earth.
The first Adam came by creation; the second Adam (Jesus) was born of a woman without sex. Adam was God’s only created son; Jesus was God’s only begotten son. Everybody between came by sex; these are the three ways that God brought life in the Bible.
All who came by sex come from thought to flesh, but Adam came from thought to Word to flesh, and Jesus came from thought to Word to flesh. We came from thought to flesh, but now through the new birth, flesh is becoming the Word.
Adam was a created son of God, therefore the offspring of Adam were to come forth by creation (not by sex).
Sons and daughters were supposed to be spoken into existence (they would have come in mature bodies as did Adam) because the veil of Eve’s womb was not to be broken; if the veil was broken then blood would be shed and God did not intend for blood to be shed.
The original marriage covenant was for multiplication by creation, it was not for multiplication by sex.
The offspring that Adam did not bring forth by the spoken Word is coming into expression via the union between the Headstone and the predestined gene of God within the elect.
