I came across this verse from the Gospel of Mark and I don't really understand it.
[31] There came then his brethren and his mother, and, standing without, sent unto him, calling him.
[32] And the multitude sat about him, and they said unto him, Behold, thy mother and thy brethren without seek for thee.
[33] And he answered them, saying, Who is my mother, or my brethren?
[34] And he looked round about on them which sat about him, and said, Behold my mother and my brethren!
[35] For whosoever shall do the will of God, the same is my brother, and my sister, and mother.
