Speaking truth into the music and art scene today can be intimidating. The gospel is so countercultural. Also, the sense is that everyone’s already heard and are not interested. Possibly one of the more intimidating obstacles is the concept that faith should be a private matter and not to be spoken of in public. Based on this assumption people will say that we shouldn’t “use” the platform of art and music to preach. Or that art with a message is propaganda.
Paul was a radical follower of Jesus. After meeting Jesus, he spent his life traveling the world, kind of like going on tour with a band, preaching Jesus and planting churches. He regularly suffered because of this.
