Mary Sinless?

Mary was actually "blameless" when "the angel said to her, 'Do not be afraid, Mary, you have found favor with God.' (Luke 1:30). Mary was like Luke 1:5-6 "Abijah; his wife Elizabeth was also a descendant of Aaron. Both of them were upright in the sight of God, observing all the Lord's commandments and regulations blamelessly." Proverbs 20:9 Who can say, "I have kept my heart pure; I am clean and without sin"? Proverbs 11:20 The LORD detests men of perverse heart but he delights in those whose ways are blameless. Proverbs 28:18 He whose walk is blameless is kept safe, but he whose ways are perverse will suddenly fall. Romans 3:23 for all have sinned and fall short of the glory of God. Romans 5:12 Therefore, just as sin entered the world through one man, and death through sin, and in this way death came to all men, because all sinned. Jesus was born without sin for one purpose: Hebrews 7:26 "Such a high priest meets our need—one who is holy, blameless, pure, set apart from sinners, exalted above the heavens. Hebrews 4:15 For we do not have a high priest who is unable to sympathize with our weaknesses, but we have one who has been tempted in every way, just as we are—yet was without sin. Mary was one of us and she was not "set apart from sinners" as Jesus was.
