The answer is: Isaiah

Isa 20:2-3

Imagine the scene: Isaiah, a true prophet of God, strutting through ancient streets, unadorned and utterly vulnerable. Nothing speaks louder than action, right? In Isaiah 20:2-3, we see him called to this disturbing yet strange mission for three whole years; he marched around without shoes or clothes as a symbolic act against Egypt and Cush, portraying the coming judgments. This prophetic act was more than a flamboyant spectacle—it provided a jarring object lesson about the power dynamics and looming invasions. Wearing nothing would have sent chills down the spines of onlookers.

This was a dramatic call to wake people up to the consequences of their own actions in turning towards alliances with foreign nations instead of deepening their trust in divine realms. Isn’t it fascinating how the stark nature of his message somehow says, “Look! Aligning with these nations may lead you to spiritual ‘nakedness’ and suffering”?

Here's a fun side note: throughout history, various prophets used unconventional methods to relay their messages, much like how Ezekiel baked bread over dung as a vivid image of hardship. And quite also in the ethos, the Holocaust survivors in Yad Vashem's "Garden of the Righteous" display walks symbolize national memory and moral duty.

These powerful acts of faith challenge and nudge us into pondering our roles in a larger societal frame—a great reminder that spirituality sometimes compels us into emotive places that resonate starkly beyond mere phrases.
