John 19:25-27 (King James Version)
25Now there stood by the cross of Jesus his mother, and his mother’s sister, Mary the wife of Cleophas, and Mary Magdalene.
26When Jesus therefore saw his mother, and the disciple standing by, whom he loved, he saith unto his mother, Woman, behold thy son!
27Then saith he to the disciple, Behold thy mother! And from that hour that disciple took her unto his own home.
And so, according to the words of Christ, at Jesus’ impending death, the disciple John was entrusted with taking care of Jesus’ aging mother.
She became NO ONE ELSE’S MOTHER.
Or Christ would have told us that.
Interesting that the Lord gave Mary's care, not to His own family members but to one of His diciples. Evidences as well that Mary needed the protection and care. If she was as powerful as is spoken of her now she is departed then I would assume she could have been powerful enough to take care of herself then. Obvious Jesus recognized clearly she had no power and put her in the care of one He trusted would do so.
