This thread is an attempt to inform on the biblical perspective of when life begins, humanly speaking.
I am not an expert on theology, biology, Hebrew, Chaldean or Greek. I would not even rate my understanding of the level of student, yet. More student-wannabe, for the time being.
Nonetheless, it is profitable for the believer to study theology and the mentioned subjects to make the issue (and attendant issues) more perspicuous.
Profit for the unbeliever is unknown; however, it is assumed those reading are--- at least--- of an open mind.
The opening chapters of Genesis utilize four verbs in describing God's creation of human life.
BARA 'to create from nothing.' Generating inorganic matter from nothing previously existing, God created the heavens and the earth, provided life to animals, and humans.
And God created [bara] man in His own image, in the image of God, He created [bara] him; male and female he created [bara] them.
YATSAR 'formed.' While Adam's life, animal life, were created from nothing, Adam in particular was unique, in that his body was formed from dust, itself already existing.
the the LORD God formed [yatsar] man of dust from the ground.
Biological life, while material, does not include a human soul, which is immaterial.
ASAH 'to make' or manufacture, after a pattern.
The God said, "Let Us make [asah] man in Our image, according to Our likeness."
The pattern was Himself, betselem and 'likeness.' Today's Hebrew echoes the ancient image, in that it speaks of spiritual similarity, rather than a physical, or bodily similarity. As such, man is not a duplication of God (blasphemous), but rather, a shadow image, invisible, but real.
WHO GIVES HUMAN LIFE?
As the image of God, human beings are endowed with rational, moral, and relational capacities, which God empowers with the spark of life. As the image of God, human beings are the only creatures who uniquely reflect God.
Our real essence, like God, can only be defined by its characteristics. Among them, self-consciousness, mentality, volition and conscience, constitute a person's soul, living within a biological body.
BANAH 'to build.' Unlike yatsar, creating out of existing material, yatsar depicts construction.
And the LORD God fashioned [banah] into a woman the rib which He had taken from the man, and brought her to the man.
Biological and soul life were given to Adam and the woman simultaneously, first to Adam, then to the woman. These four verbs designate two of the three categories of life.
