While he was speaking, a woman from the crowd called out and said to him, "Blessed is the womb that carried you and the breasts at which you nursed." He replied, "Rather, blessed are those who hear the word of God and observe it." (Lk 11:27-28)
Jesus was speaking to a crowd. There were many people who were listening to Jesus. Jesus attracted the people by his speech. People also liked the content of his speech because he spoke with authority and also he spoke of the kingdom of God and the presence of God in the world. He teaching was new with new content and it communicated god to the people.
A woman in the crowd cried out. A single person was inspired by the speech and poured out her experience. It was like the Baptism experience at the hand of John the Baptist. There voice from the heavens said “This is my beloved son in whom I am well pleased”. At Baptism God the father owned up the son here the mother of Jesus is owned up by the crowd (a voice in the crowd).
Jesus’ reply was great. Mother was not his model or the guiding force of his life rather the word of god. Jesus took his formation from the word of God. This we have seen at the end of his forty days of prayer in the wilderness. He said “man does not live on bread alone but by every word that comes from the mouth of God. Word of god was his life and the source of his life and the goal of his life.
