The theme in the song above is that though a loved friend or relative, or perhaps both is gone, you will see them again. You will miss them but you just need to power through your grief and pain. Just keep in mind that though you can not see them now, eventually you will. Keep faith, constantly remind yourself of this possibility. But, even though the pain of remembering the ones who have gone is hard, you must remember them or else they are gone to the word, and soon enough to yourself. Carry them wherever you go, keep that pain as a reminder of the joy you will soon feel when you see them again.
