Interesting question. Thanks.I'm curious on how the breath of life sustains people who are considered as spiritually dead. Like in the valley of dry bones. In that valley were bones of people who may still have been walking the earth but they were spiritually dead. Are all people basically on something like spiritual life support from God to keep them from just dropping dead on the spot like Ananias?
In my view, the breath of life sustains physical life only.
If we think about childbirth, a soul (personal identity) is created at conception. (DNA)
The breath of life does not happen until the child is born and takes its first breath?
Thus beginning the lifelong journey of physical life. (outside the womb)
Or, alternatively, the breath of life only applies to Adam. not anyone else.
(since physical/spiritual life begins at conception.
Sorry, I don't think I really addressed your question.
But felt that I needed to lay some foundational groundwork first.
