What does the Bible say about children of the lie?

In John 8:44, Jesus declares to a group of Pharisees, 'Ye are of your father the devil.' This stark statement reveals that not all people are children of God, as many assume. Instead, those who reject Christ and adhere to lies are described as the children of the devil, demonstrating that allegiance to truth is what defines God's children. This notion is rooted in the biblical understanding that many individuals, despite their moral or religious appearance, could still be deceived by false teachings and therefore classified as children of the lie.
