Yeah i agree. Of course religious imagery is mostly used because they sound poetic. And i realize i'm in a minority seeing the world through pretty strongly atheistic (and non-spritual) eyes. But the lyrics in the ending of Surrender to Reason has always sadly made me appreciate such a great song a little less.
I can understand this. As an atheist myself (who studies the intersection of religion, philosophy, and society) the more overtly "spiritual" lyrics do create a disconnect between me and the songwriter. Messages about the strength and power of faith -
belief in empirically unverifiable realities - certainly don't resonate with me. However, as others have pointed out, it seems that DT consciously tries to avoid overt religious imagery in their lyrics so as to not alienate listeners while still writing music and lyrics that are meaningful to them. I can appreciate and respect that.
The disconnect I feel doesn't really matter for a variety of reasons - 1) the songwriter said what mattered to them, and I can relate with the strong emotions people feel in life anyway, 2) I feel like my enjoyment of a song shouldn't be contingent on whether I agree with the cosmology it's founded upon, especially because at the end of the day I prioritize music over lyrics, 3) the lyrics' internal structure reveal patterns, poetry, and other constructed delights I can enjoy, 4) I can use the song the study the influences religious and spiritual belief systems have upon art, etc.
All that being said, I can't deny it's nice when I listen to things which I can viscerally relate to.
