Who's your daddy? is a slang expression that, in one use, takes the form of a rhetorical question. It is commonly used as a boastful claim of dominance over the intended listener. It is a question we need to ask ourselves in the spiritual, emotional and psychological realm. It could be said more like, "Who controls you?" or "Whose authority are you under?" The apostle Paul asked this question in his own way over 2000 years ago.
