The answer is: Isaiah

Isa 20:2-3

In the book of Isaiah, we stumble upon one of those eye-catching moments that grab our attention — the prophet walking around barefoot and naked. Imagine that for a moment! God commands Isaiah to strut his stuff for three whole years as a symbol. Why? He wanted to illustrate the vulnerability and impending doom faced by the nations Israel and Egypt. This act was a dramatic and shocking way to convey a prophetic message and called attention even in the ancient day.

Digging a little deeper, we find out that nudity in the Bible often symbolizes shame or disgrace. In contrast, Isaiah's prophecy was meant to expose the shameful behavior of these nations and ingrained the serious nature of what was to come. What's fascinating is how much time this involves—three years. Isaiah, just like other biblical figures, faces significant trials to relay a greater message. It's almost like the ultimate unfiltered form of performance art!

Additionally, in the same breath, we can think about how nudity shows openness, a lack of pretense. Isaiah bared not only his body but surely his heart to follow God's will. This echoes throughout the Bible, where figures like John the Baptist, with his rough wardrobe, or even Adam and Eve before the Fall, exemplify a raw kind of existence before God.

Isaiah’s unorthodox mission gives us a rhythm in what it means to be naked—both symbolically and literally—all in service of living out one's purpose, no matter how quirky it might seem.
