Mark 3:31-35

31Then His mother and His brothers arrived, and standing outside they sent word to Him and called for Him.

32A crowd was sitting around Him, and they said to Him, “Look! Your mother and Your brothers are outside asking for You.”

33And He replied, “Who are My mother and My brothers?”

34Looking at those who were sitting in a circle around Him, He said, “Here are My mother and My brothers!

35For whoever does the will of God [by believing in Me, and following Me], he is My brother and sister and mother.”
