Do you beleive that you can be fooled by "Satan" who comes as everything your expecting? everything?
1. There is a Satan in Judaism. However, he is a the prosecutor/entraper of man, not an enemy of God.

2. Yes, I do fear the possibilty that a false Messiah may come and leave nothing but death and destruction in his path.
Now let me ask you a question. Do you ever fear that you are praying to a false Messiah who committed blaspheme and cannot be teh "Son of God"/God if God's word is true?
I doubt it.
Or let me put it this way, if in your lifetime a leader who brings Peace the re-building of the temple is done the Jews have there homeland, if this happens in your life time will you have any any thought at all this might be the Anti-Christ "Satan" or will you not even question that in your mind.
Only if he breaks the Law, tries to supercede it, or proclames himself a diety.
