Jesus’ biological mother and brother thought that they should have privileges that would outweigh the others that served him. 
But Jesus took this opportunity to make known that he didn’t favor some more than others. He stood in the crowd and declared the entire group of disciples as his family. 
You are just as important to Christ as the next person. He lived and died for you–just like he did for others. Jesus loves us all.

Matthew 12:46-50
