Lyric discussion by OctaVariuM8 

See, I have a different thought on the meaning of this song. The narrator is going through a tough bout with a disease or something and his wife/spouse is not there to comfort him/her. As seen by the "thirty years" part and rising and falling of their marriage. You could also go into the literal meanings of "blood heal me" being transfusions, and "fear change me" being his experiences in this situation changing them for the better.

I mean parts of it start to fall apart, and it is not the perfect interpretation, but it is the one I have been getting lately (been listening to the song for probably close to 8 years now).

@OctaVariuM8 That sounds more reasonable. The part where it says "Belief will always save me" also enhances that with a touch of religious faith that he ,The narrator, Believes will save him. He is not alone thought As heard hear: People in prayer for me Everyone there for me Sometimes I feel I should face this alone My soul exposed It calms me to know that I won't. There are other people there praying for his well being and being their for him but the wife part does completely make sense
