What does the Bible say about the family of God?

The family of God is defined by spiritual relationships rather than earthly ones. In Matthew 12, Jesus illustrates this by stating that His true family consists of those who hear and do the word of God. This is a clear departure from the religious understanding that all who are physically related are part of God's family. In essence, Jesus emphasizes that spiritual kinship supersedes physical kinship, underlining that those who obey His teachings are His true brothers and sisters. As articulated in Hebrews 2:11, Jesus is not ashamed to call us His brethren, emphasizing a profound and eternal connection that transcends earthly relationships.
