I think people who are christian would argue that jesus isnt saying 'believe in me or i will condem you". They would argue that we are already condemned and jesus is offering to save...
the problem is the original condemnation comes from the person jesus is claiming to save us from, either himself or his father, depending on your brand of christianity. Its all so obtuse, that we are condemed for something we didnt do (adam and eves sin) and that sin from thousands of years ago means we deserve to die unless another guy dies and makes it ok. So because the other guy died the sky daddy can 'forgive us' but couldnt just forgive us because we didnt do anything wrong in the first place.....
Btw the WT article that prompted this thread was a misprint. A letter to the BoE says it should read "jesus shaves!"
