I like for King and Country a lot. And while I like staying very close to the Biblical texts, I’ve noticed that the Pentecostal movement has a different theology, which is simply to say they are discussing the scriptures in a different way than I’m accustom to.
To your point, Cain does not retell the biblical account of Lazarus, in their song “Rise Up”, but instead, it seems to me they use the story in a similar way as an object lesson, which should encourage, and empower us to “come out of our grave”, metaphorically anyway.
I do enjoy the song, and my wife has led it in worship multiple times.
