Lyric discussion by Colin_Betts 

Cover art for Taxi Cab lyrics by Twenty One Pilots

I just don't think his songs are strictly about his faith. I really like the idea of the rap being a suicide attempt- and him finding his way back to sanity- which he needed his faith to do, and relied on that. But I don't think any of his songs were written strictly about his faith. They're not a Christian band, but he does express his faith freely.
