Loving our enemies isn’t a big deal

I think I woul dissagree a bit on that, but it all depends on the different circumstances. If you are just treating people nicely and you don't get the same response back is totally understandable and we should not expect anyhing back anyways when we treat people nicely.
But there are situations when people abuse you, hate you, beat you, steal from you, or kill your loved one. These kinds of people would be super hard to love or forgive.
