31 Then Jesus' mother and brothers came to see him. They stood outside and sent word for him to come out and talk with them. 32 There was a crowd sitting around Jesus, and someone said, "Your mother and your brothers are outside asking for you." 33 Jesus replied, "Who is my mother? Who are my brothers?" 34 Then he looked at those around him and said, "Look, these are my mother and brothers. 35 Anyone who does God's will is my brother and sister and mother."

It is a great comfort to all true Christians, that they are dearer to Christ than mother, brother, or sister as such, merely as relations in the flesh would have been, even had they been holy. Blessed be God, this great and gracious privilege is ours even now; for though Christ's bodily presence cannot be enjoyed by us, his spiritual presence is not denied us.
