There was a man in the land of Uz, whose name was Job; and that man was blameless and upright, one who feared God, and turned away from evil. Job 1:1
Job was blameless, Noah was blameless and righteous (Gen 6:9), Abraham was blameless (Gen 17:1), Hezekiah had a perfect heart (2 Ki 20:3), Zechariah and Elizabeth were righteous (Luk 1:6), and Joseph was a just man (Mat 1:19).
...since all have sinned and fall short of the glory of God... Romans 3:23
Let's avoid the Mary question altogether here and talk about the people the Bible says are righteous, blameless, and otherwise perfect. It doesn't say they are trying hard to please God, it doesn't say they've placed their faith in God, it doesn't say anything aside from indicating they were indeed free from sin. What is going on here?
(Yes, I realize the hilarity of asking a question like this when I have 1.5 readers. But someday, someone will be able to answer my question!)
