[Diligent]

Here's another interesting verse to consider (as if Luke 1 weren't enough with John, less than two months conceived, responded to the presence of his Saviour who was only an embryo of a few days):

Judges 13:7 But he said unto me, Behold, thou shalt conceive, and bear a son; and now drink no wine nor strong drink, neither eat any unclean thing: for the child shall be a Nazarite to God from the womb to the day of his death.

How many humans without spirits or living souls does the Bible say are a "child... to God?"

And this:

Isaiah 49:1 Listen, O isles, unto me; and hearken, ye people, from far; The LORD hath called me from the womb; from the bowels of my mother hath he made mention of my name.

Or this:

Jeremiah 20:17 Because he slew me not from the womb; or that my mother might have been my grave, and her womb to be always great with me.

I read through the list of verses regarding spirit and breath. I still didn't see any that said when in human development the spirit is given to a man. Since the Bible more than once assigns human personality traits and descriptions to the unborn, is it not prudent to start with the assumption that the spirit is there unless otherwise contradicted?
