31 Then His brothers and His mother came, and standing outside they sent to Him, calling Him. 32 And a multitude was sitting around Him; and they said to Him, "Look, Your mother and Your brothers are outside seeking You." 33 But He answered them, saying, "Who is My mother, or My brothers?" 34 And He looked around in a circle at those who sat about Him, and said, "Here are My mother and My brothers! 35 For whoever does the will of God is My brother and My 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.
