When it was already dawn, Jesus was standing on the shore; but the disciples did not realize that it was Jesus. (John 21: 4)
Now that very day two of them were going to a village seven miles from Jerusalem called Emmaus, and they were conversing about all the things that had occurred. And it happened that while they were conversing and debating, Jesus himself drew near and walked with them, but their eyes were prevented from recognizing him. (Luke 24: 13-16)
If Jesus were to appear to you today, would you recognize Him? What would you say to Him? How would you act?
I don't think He'll have a name tag that says, "Hello, my name is Jesus Christ." (Although that would make things very easy for us.)
No, I would hazard to guess that we would not recognize Him if we saw Him. We only know that He is God. And that's all that's important.
Since we don't know what Christ looks like, how do we resolve the dillemma of recognizing Christ if we ran into Him?
The answer is really quite simple.
We treat every person as if they were Christ.
