Would we recognize God’s speaking through people today in this way, or just dismiss it because it is not what we expect from Him?
“at that time the Lord spoke through Isaiah son of Amoz. He said to him, “Take off the sackcloth from your body and the sandals from your feet.” And he did so, going around stripped and barefoot.  Then the Lord said, “Just as my servant Isaiah has gone stripped and barefoot for three years, as a sign and portent against Egypt and Cush,  so the king of Assyria will lead away stripped and barefoot the Egyptian captives and Cushite exiles, young and old, with buttocks bared—to Egypt’s shame.”
-Isaiah 20:2-4 (NIV)
Get uncomfortable with this and then consider what the original creative mind of God would come up with to get your attention. What customs and traditions are you relying on for your comfort, but others use to dismiss your actions as false piety? We are made in the image of God, not the image of a parrot. Listen to Him and be creative, because He created first.
