The bible does not say at birth. You will have to quote scripture to convince me otherwise. I know you will not be able to present any scripture to verify your claim.
See #50. I don't think to persuade anyone to agree with me. What I do think to do is show that there is scriptural basis for someone to believe that the Bible teaches that life begins at birth -- when breath enters the body.
And that is certainly what I believe, and why I believe it.
