Cover art for God Is in the House lyrics by Nick Cave and the Bad Seeds

For me this song is not about whether God is present or not, it is about how many christians forget the real message of Jesus. Jesus himself spent a lot of time with those who were rejected from society, he even went so far to claim that that was one of his main purposes. The people in Caves song are like the pharisees in the gospels, they reserve the holy for the righteous and successful. They think that God will punish them if they are associated with the rejects of society. So basically God is in the House is a satirical portrait of self-righteous christians who have forgotten the message of the man/god they worship.
