Mark 3:31-35

And his mother and his brothers came, and standing outside they sent to him and called him. And a crowd was sitting around him, and they said to him, “Your mother and your brothers are outside, seeking you.” And he answered them, “Who are my mother and my brothers?” And looking about at those who sat around him, he said, Here are my mother and my brothers! For whoever does the will of God, he is my brother and sister and mother.”

Those who sat at Yeshu’s feet to learn how they may obey God, they were His real family; it is what he said.

As for those who believe in Him today, 2000 years later, and seek to do God’s will, though they are not His Jewish relatives, yet He calls them His own true family.
