God is dead. God remains dead. And we have killed him. The important idea here is Nietzsche's treatment of the Christian God as an absurdity, that is, the enemy of life and nature. This idea has greatly influenced the lyrics of industrial musicians, especially in those of Nine Inch Nails and Gary Numan.
Industrial music is in a mode of being philosophical.
Almost every industrial bands' lyrics are religious, anti-religious, philosophical, or nihilistic. While Numan is not necessarily interested in denouncing religion, he appears to be interested in discovering new ideas in his music by writing lyrics that consider a dead God. Numan obviously does not believe that God is literally dead, as he often sings about killing God, something that couldn't literally be done. While Numan does not mean this in a theological sense, the influence of Nietzsche is obvious. In other words, Jesus experienced an existential crisis in a debate of whether to follow the destiny that is planned for him or choose free will.
