Isaiah 20. A very short chapter, only 6 verses, but full of meaning and impact.
It may sound a little weird, but God tells Isaiah to take off his sackcloth and his sandals. For three years Isaiah walked around "stripped and barefoot." This prophet of God literally walked around naked for Three Years because God told him too. His actions were meant to symbolize a warning to Egypt and Cush of a coming disaster.
How difficult this must have been for Isaiah. Walking around naked for anyone to see. I am pretty sure this would have been quite embarrassing. Isaiah certainly would have been ridiculed and mocked. Laughed at and scorned. Yet, Isaiah did this because God told him to. He was willing to be obedient, despite the mockery and shame it would bring. It was Gods way of delivering the message the people needed to hear.
I imagine Jesus listening to this story and maybe having some reasonable questions, like: Why did Isaiah have to be naked? Why would God ask him to endure that shame and embarrassment? Couldn't the message have been delivered another way?
