Luke 8:19 Now Jesus' mother and brothers came to see him, but they were not able to get near him because of the crowd.
Matthew 12:46 While Jesus was still talking to the crowd, his mother and brothers stood outside, wanting to speak to him.
Mark 3:31 Then Jesus' mother and brothers arrived. Standing outside, they sent someone in to call him.
Luke 8:20 Someone told him, "Your mother and brothers are standing outside, wanting to see you."
and to take away the silly argument that "brothers" means friends and not blood relatives that came from his earthly parents:
Luke 8:21 He replied, "My mother and brothers are those who hear God's word and put it into practice."
here He makes the distinguished difference for us. Brothers are now not just those who were carried by His mother, but those that obey and are included in the family of God.
