LUKE 24:16

 but they were kept from recognizing Him. - Luke 24:16

Nicely played!  I am not exactly sure why You would not want to be recognized or what You even looked like, but how cool is that!  A random guy just starts walking along the disciples (weird) and then asks them what they are talking about (You already knew), and then starts explaining things to them (guys had to be freaking out at this point) and then.......BOOM!  THE REVEAL!

So, do You still do this?  Do you sometimes come down here and walk amongst us, disguising Yourself?  Are there possibly even some times that You are talking to us about You?  Not sure if You do, but I know this - I am gonna freak out if some random dude starts walking next to me on the way to work!
