If Jesus Christ walked through your door right now, what would you say to him?

I'm saying to the OP: How am I to know it's Jesus?  Am I supposed to assume that he looks like the typical artist's rendition?

So, I'd probably say, "Can you prove that you are THAT Jesus in a way that doesn't look like just a magic trick?"

I have seen some magic on "America's Got Talent" that seems completely impossible, so, I'm admitting that it would take something incredible -- and then I'd have to wonder if I'm having a hallucination.

So, generally, I want a demonstration that the whole world can see -- such as changing the orbit of the Earth, without disruption, so that a solar year is exactly 360 days.

So, maybe what I'd say is, "You KNOW what I want you to do." 

Wipe your feet! Were you born in a barn?

How in the hell would I know it was Jesus Christ?....Now. If he walked across my swimming pool, I would definitely think about it.

“Let’s go out and get nailed...”

If some middle eastern guy (who presumably could only speak ancient Hebrew or Latin) burst in to my house, I'd be calling the police to have him arrested.

Not that there is any actual proof that such a person ever existed - the biblical stories were not created until 100 - 300 years after the supposed events.

Also, the Romans, who were meticulous record keepers, never mentioned any of the supposed events or execution.
Fairy stories, in other words.

My kids would walk into my room all the time. So I would probably not actually look and just say. (Yessss! ) like, if I already know that they want something from me. 

What the Hell took you so long?  Why are you here when you need to be out there curing the sick and quelling riots?

Knock next time, ya rude b@stard

Either
"Who are you?"
or
"Can I help you?"

I will be shocked, but I will fall on my knees and bow down to Jesus and say "Thank You Lord."

Since he never existed I would put a cap into someone's butt.

Sir, why are you breaking into my house? What an impudence! 

お帰りなさい

Thanks for asking.

"What gives, dude? I worship you for years and you didn't say nothin'."

The last time Jesus unexpectedly dropped by, I was speechless. In fact, Jesus (literally) scared the hell out of me. 

"Hi.  Sit down.  Let's talk".

why is god so cruel ?

Why they get the path so wrong lord . I am Tibetan Buddhist and a universalist.

Coffee or tea ?

You're welcome

Stop trailing clouds of glory all over my clean floor!!!

Where have you been, you're 2000 years late....

Nice to see you again

Very glad you're back. And not a moment to soon. 😀

I'd follow the excellent example of the disciple Thomas, who had Jesus suddenly appear in the room (though the door was locked). He exclaimed, "My Lord and my God!" I'd say the same, falling on my knees before Him.
