What does the Bible say about the family of Jesus?

In Luke 8:19-21, Jesus redefines his family, emphasizing that those who hear the word of God and do it are his true brethren. This statement reflects a shift in focus from biological ties to spiritual relationships, suggesting that faith and obedience forge a more significant bond than mere lineage. Throughout the Gospels, Jesus illustrates that his mission and divine duty take precedence over earthly family connections, which culminates in the establishment of the spiritual family of believers.
