“[26] When Jesus therefore had seen his mother and the disciple standing whom he loved, he saith to his mother: Woman, behold thy son. [27] After that, he saith to the disciple: Behold thy mother. And from that hour, the disciple took her to his own. John; Chapter 19
Christ instructed John to take Mary as his own mother. He did so. Christ said to his mother, John is your new son.
This does say anything beyond this.
“But then again, some people like to cherry pick the Bible. “
I wouldn’t accuse you or anyone of cherry-picking this passage and just to make it say things it does not. I’m just pointing out that it doesn’t say more than it actually says.

What part of that do you not understand. Was John lying? Was Mary not Jesus' Mother? Or is the Bible in error? Or is Jesus not God?
