Who Is Jesus' True Family?

Matthew 12:46-50

While he was yet speaking to the multitudes, behold, his mother and his brethren stood without, seeking to speak to him.

And one said unto him, Behold, thy mother and thy brethren stand without, seeking to speak to thee.

But he answered and said unto him that told him, Who is my mother? and who are my brethren?

And he stretched forth his hand towards his disciples, and said, Behold, my mother and my brethren!

For whosoever shall do the will of my Father who is in heaven, he is my brother, and sister, and mother.
