Jesus wasn’t being disrespectful. He was simply showing the difference between His blood family, and His spiritual family. Elsewhere in Luke we can find Him repeating this notion when He says, “Blessed are those who hear the word of God and obey it.” (Luke 11:28) When we become a Christian, we are adopted into and become part of the family of God. And part of being in this family is listening to the word of God and then applying it to our own life…practicing until it becomes a habit.
