I'm a bit confused as to what's meant by "enemies".
There's three interpretations I can think of:
- One is a reference to World War II and other events. I'm not what nationality the speaker is, but I'm guessing either American or South Korean, both of whom would have regarded Japan as a past enemy. I don't know whether Christians regard the phrase "love your enemies" as being relevant to people from enemy countries - that sounds like a secular rather than a religious matter.
- One is a reference to those who persecute Christians. This doesn't seem plausible to me, because although Japan is predominantly non-Christian, that doesn't equate to persecution. I suspect there's more hostility towards Christians in Australia or the United States than in Japan!
- Wikipedia mentions an interpretation of all heathens as being "enemies". But this has a  after it.
None of the interpretations seem that plausible. What's being meant here?
