This is for those who insist that Mary never sinned and was always in God's will.
Mary was blessed to be chosen by God but she did not always do His will. There was at least this one time mentioned below but the way she responded to him when He stayed behind at the temple when He was 12 and at the wedding feast at Cana of Galilee were likely other times too. While he yet talked to the people, behold, 👉his mother👈 and his brethren stood without, desiring to speak with him.  Then one said unto him, Behold, 👉thy mother👈 and thy brethren stand without, desiring to speak with thee.  But 👉👉👉he answered and said unto him that told him, Who is my mother? and who are my brethren?  And he stretched forth his hand toward his disciples, and said, Behold my mother and my brethren!👈👈👈  For whosoever shall DO THE WILL OF MY FATHER which is in heaven, the same IS MY brother, and sister, and 👉MOTHER👈. Matthew 12:46-50 Jesus was explaining that His mother, at least at that time, was not doing God's will but those who were with Him were. Other potential situations that Mary may have not been perfect in her responses... And the third day there was a marriage in Cana of Galilee; and the mother of Jesus was there:  And both Jesus was called, and his disciples, to the marriage.  And when they wanted wine, the mother of Jesus saith unto him, They have no wine.  Jesus saith unto her, Woman, what have I to do with thee? mine hour is not yet come.  His mother saith unto the servants, Whatsoever he saith unto you, do it. John 2:1-5 And when he was twelve years old, they went up to Jerusalem after the custom of the feast.  And when they had fulfilled the days, as they returned, the child Jesus tarried behind in Jerusalem; and Joseph and his mother knew not of it.  But they, supposing him to have been in the company, went a day's journey; and they sought him among their kinsfolk and acquaintance.  And when they found him not, they turned back again to Jerusalem, seeking him.  And it came to pass, that after three days they found him in the temple, sitting in the midst of the doctors, both hearing them, and asking them questions.  And all that heard him were astonished at his understanding and answers.  And when they saw him, they were amazed: and his mother said unto him, Son, why hast thou thus dealt with us? behold, thy father and I have sought thee sorrowing.  And he said unto them, How is it that ye sought me? wist ye not that I must be about my Father's business?  And they understood not the saying which he spake unto them.  And he went down with them, and came to Nazareth, and was subject unto them: but his mother kept all these sayings in her heart. Luke 2:42-51 It is Jesus' responses to her that indicates there may have been issues... At the onset, when she was chosen by God, Mary recognized that she needed a Saviour and at His resurrection as well, I believe, but there were struggles between those two times as Jesus clearly pointed out. If you have doctrine built on Mary never having sinned then you need to repent of that doctrine and start believing God's Holy Word as He originally intended it to be believed. For there is one God, and one mediator between God and men, the man Christ Jesus;  Who gave himself a ransom for all, to be testified in due time. 1 Timothy 2:5-6
