We are aliens in this world. 1 Peter 2:11

This was the t-shirt that our family and another family wore to Epcot. The shirts were lime green and on the front they had 3 eyes. Over and over people asked, "Why the eyes?" We would show them the words on the back and you could immediately tell if the person was a Christian. One lady said, " You are speaking my language." Other responses were "O-o- o K-k-k?" " That makes sense, I guess?" People tried to act like they understood, but if they didn't get it you could tell. I want to come up with a way to respond that would lead a person to Christ and not just confuse them.
