What Jesus himself had to say about “HIS MOTHER”(and other relatives).
“Matthew 12:46While he yet talked to the people, behold, his mother and his brethren stood without, desiring to speak with him. 47Then one said unto him, Behold, thy mother and thy brethren stand without, desiring to speak with thee. 48But he answered and said unto him that told him, Who is my mother? and who are my brethren? 49And he stretched forth his hand toward his disciples, and said, Behold my mother and my brethren! 50For whosoever shall do the will of my Father which is in heaven, the same is my brother, and sister, and mother.”
So if any of us do the Father’s will, we will be considered as though we were his “mother, sister and brother”! This passage alone shows us the “relative” value that he placed upon his family, comparing our relationship to the Father to his relationship with his own family!
This verse has been mentioned before. I’m not sure why Jesus made this statement, but it did not change the fact that Mary was the mother of Jesus.
