the problem with eschatology (end time theology) is the "RAPTURE", there's only one verse that talks about us meeting Jesus in the air, but an entire theology is based on this. When in fact Christ's final destination is planet earth, since heaven is clearly moving down here. Besides which, it is the passing away of HEAVEN AND EARTH that "No man knoweth the hour" NOT the time of Christ's return - there's too many clues indicating the signs of his return, none of them based on the date of creation or Noah's flood as these guys have done
