This poem warns of the dangers of apostasy and losing one's faith. It describes how doubting thoughts can lead one astray down a "tunnel" away from God and toward the "devil". It says that this process happens slowly, as faith is "licking" away until one's spirit is "hollow". The poem suggests that by abandoning faith, one crucifies "the son again" and becomes "nothing but a fallen angel", segregated from heaven, with redemption no longer possible.
