Kanye is forcing the conversation, and he’s doing it with the Gospel. Kanye isn’t telling the world they’re sinful and they need to repent, he’s telling them who Jesus is. He’s telling the world that Jesus was sent by God to die for them because God loves them. Believe it or not, millions of people still don’t know that. Their only encounter with Jesus has been through judgmental Christians that give them condemnation rather than mercy.
Think about how many celebrity Christians are radical for Jesus. Not many right? We see lots of public figures profess their faith or acknowledge Jesus when they win a football game, but how many high profile people are radically evangelizing the world for Jesus?
Most people that are famous walk their faith back a bit. They'll acknowledge Jesus but make concession for other beliefs. Especially politicians, most of them don’t want to offend people or lose votes so they don’t use their platform to encourage people to receive Jesus and be born again.
