Warn Other Shepherds!
Every father is the “shepherd” of his family. He has the responsibility to guard his own flock from the destruction of false prophets, and he also has the responsibility to warn others about the dangers he sees. This is clearly mandated in Scripture.
“If thou faint in the day of adversity, thy strength is small. If thou forbear to deliver them that are drawn unto death, and those that are ready to be slain; If thou sayest, Behold, we knew it not; doth not he that pondereth the heart consider it? and he that keepeth thy soul, doth not he know it? and shall not he render to every man according to his works?” (Proverbs 24:10–12).
