Again, Job 1:1 says, states as a firm fact that Job was a perfect man. Do you deny this?
Does not the OT state that (at least) one man was perfect and that he was Job?
My version says "blameless", but there is an interpretation to be made. Do you believe that since Job was "perfect" that he was sinless? I believe Job may have been righteous in a similar way that Abraham was, but we know that Abraham sinned.
