Long before sociologists began dissecting the concept of identity, the Bible recognized our innate longing to be known. In Scripture, names were more than labels; they were declarations of relationship to God, the ultimate standard for identity. Names reflected value, character, authority, and purpose—each one a signpost pointing to a God-given role. 

Social media has become a mirror reflecting our fascination—some might say fixation—with identity. Every online profile starts with a “handle,” the chosen name by which we wish to be recognized in the digital world. Some of us stick with our real names, while others invent new monikers, each username a subtle declaration of our values, interests, and aspirations. Just beneath that handle, we labor over our “bio,” a carefully curated summary of who we believe ourselves to be and how we hope to be perceived.

Of course, the need to introduce ourselves is nothing new. Long before the age of tweets and timelines, our names and short descriptions were the first things we offered when meeting strangers at a dinner or gathering. But before the internet, opportunities to publicly define ourselves were rare. Now, with every post, photo, and update, we reinforce the identity we’ve crafted. Social media thrives on these repeated, public declarations of self. We build our profiles with intention, then feed them with content that amplifies the persona we want the world to see.

When I talk about “identity,” especially from my perspective as a detective, I’m aware of two distinct meanings. In one sense, identity can be established by hard evidence.
