So I think I figured out the meaning of the lyrics. When he says "there's a limit to your love", he means it in a sarcastic way, he really means there is no limit to your love. Why I think this is right after he says "like a water fall in slow motion," water falls pretty much go on forever and one in slow motion would last way longer. And on a land map oceans act as the borders because there is no more land to go to. A map with no ocean wouldn't have a limit on it.
