I don't think the song is so much about "proving your love". I think the speaker is making unreasonable demands for love. Like, "Suffer some misery" and "Risk your health for me...if you want my love".
I also think the lines: "The narrowest path / Is always the holiest" might suggest that limiting yourself and not expanding leads the subject to being "holy". The song appears more sinister than spiritually moving.
