In the gospel of Matthew Jesus was still talking to the crowd about not blaspheming the Holy Spirit and told the story about a person who had seven evil spirits return when his family appeared. His mother and brothers asked to talk with him. Luke said that they could not get to him because of the crowd.
But he replied to the man, “Who is my other, and who are my brothers?” (Matthew 12:48 ESV). He then pointed to his disciples and said, “Here are my mother and my brothers! For whoever does the will of my Father in heaven is my brother and sister and mother” (vs 49, 50). Matthew, Mark, and Luke all have one thing in common with this story: this story is sandwiched between Jesus’ speeches about not hiding/squandering their faith.
Those stories include the parable of the sower, the parable of the weeds, the parable of the hidden treasure, the lamp under the stand, and so on. Jesus’ point that those who do the will of God are his family members was reinforced and even magnified by all the parables the precede and follow. It’s clear that Jesus puts the most emphasis on being doers of God’s word. He also makes a strong contrast between those who get “chocked out” of their faith by the worries of this world and those who set their roots down deep and grow. Being doers of God’s will requires tremendous discipline.
