Jesus, some Miracles, and a few holes.

"For there shall arise false Christs, and false prophets, and shall shew great signs and wonders; insomuch that, if [it were] possible, they shall deceive the very elect. " Matthew 24:24

"13: For such men are false apostles, deceitful workmen, disguising themselves as apostles of Christ.
14: And no wonder, for even Satan disguises himself as an angel of light.
15: So it is not strange if his servants also disguise themselves as servants of righteousness. Their end will correspond to their deeds. " 2 Corinthians, chapter 11:13-15

"
9: The coming of the lawless one by the activity of Satan will be with all power and with pretended signs and wonders,
10: and with all wicked deception for those who are to perish, because they refused to love the truth and so be saved.
11: Therefore God sends upon them a strong delusion, to make them believe what is false,
12: so that all may be condemned who did not believe the truth but had pleasure in unrighteousness. " 2 Thessalonians chapter 2:9-12.

So it looks like God did see this sorta deal of the false prophets and such coming up. I'd start to question (to a degree) and look at his hands and feet to see the wounds from the cruxifiction, however this wouldn't be concrete proof, since if such a person were to be able to perform "miracles", it's quite possible that they would alter their body in a way to make a mock injury of these.

I don't think it's so much the questions that will be a litmus test, since if you were to throw bible questions at the individual, they would have already somehow used their supernatural powers to memorize what's in the bible with head knowledge. I'll give this more thought and get back.

Jam it back in, in the dark.

It's true that peoples actions speak louder than words and set the type of fruit to be produced in one's spirit, metaphorically speaking. However, this fake Jesus could have been doing good deeds here and there. Perhaps it's when this individual will do good deeds and the like purely to attract attention then announce that he's God's son that has come down for the second time, then that's where I'd question. If my memory serves me well, Jesus never like to draw big attention to himself, but not to say he didn't like to do public speaking (see talking too and feeding the 4000 and 5000 crowd), but I haven't read in scripture where Jesus will just blurt out "HEY LOOK AT ME, I'M AWESOME! LOOK AT THESE MIRACLES I DO! WOOT!" sorta fashion.

As well, it's noted in the Revelation that quite a few events are prophesized to occur prior to his arrival with the trumpet blast and tribulation. Which exact events to occur, I don't know.

There's nowhere I can't reach.

Then I'd make him turn my glass of lemonade into the best damn tasting rum ever. WIN! I believe!

This thing is sticky, and I don't like it. I don't appreciate it.
