'Sin' is a weird word. Backwards, it is 'Nis', which rhymes with 'Piss'. And take out the last letter and replace it with an 'H'. Then 당신 have 'Pish'. And if 당신 rearrange the letters a certain way, 당신 get 'Ship'. And if 당신 take out the 'P' and replace it with a 'T', 당신 end up with 'Shit'. So I guess 당신 are in deep 'Shit' with God if 당신 'Sin'. But I don't believe in that stuff anyways, so...
