The concept of 'rapture' is new one on me, and not somthing we covered in RE at school. But, am I correct in saying that fanatical types see it as the bit before judgement, when believers (and non believers, somehow, as long as they haven't activally rejected religion but just remained quiet) get swept up to heaven, leaving the rest of mankind on earth. Presumably to live happily ever after without religous interefence...
But, where does the second coming fit in to this? I assumed, perhaps incorrectly, that that's when jesus returned to earth. If so, that's a bit disappointing for believers, who have already been swept up to heaven, where jesus presumably used to be and therefore have just missed him. So, they don't get to see jesus when on earth, and then when they to heaven jesus has already left... And, worse than that, non believers get his presence amongst them!
