Hardcore_newbie, as in all religions should be, I think it's just a matter of faith, and maybe some knowledge... I just think that if you know Jesus enough, and have enough faith, you won't be fooled...

Also, it comes to my mind this bible passage, and I think you will understand:

Matthew 7:16 (King James Version)
"Ye shall know them by their fruits. Do men gather grapes of thorns, or figs of thistles?"
