This song can be about two people who are physically far apart, possibly continents because of the 'sea that divides us' because the "Moon is risin', and your Sun is shinin' down" they are in drastically different time zones and cannot share time the same. They miss their partner and wonder now with the time they are apart if they miss them the same. He or she yearns to be physically close to that person, but the current situation doesn't allow it. But the song points out that the 'bridge will bring us back together', meaning one day they should see each other.
