***According to Scripture, Job committed no sins***
Really?
Job 42
Then Job answered the LORD, and said... I have heard of thee by the hearing of the ear: but now mine eye seeth thee. Wherefore I abhor myself, and repent in dust and ashes.
"...repent in dust and ashes."
Only sinners repent.
***and the parents of John the Baptist also committed no sins (Luke 1).***
Again, not true. See post #169

Yes, really.
At Job 1 and Luke 1, Job, Zecharaiah and Elizabeth all start the show sinless. Job and Zecharaiah sin later on, by doubting and having weak faith, but at the opening, they were sinless.
Obviously this creates a theological problem. For if they were born totally depraved, how was it that they avoided sin up to that point in life? But if they had sinned in their lives, how were those sins wiped clean before the Christian dispensation?
