As for the music on my sidebar, the lyrics to the hip-hop selection that is in the vein of Isaiah 6 and that quotes Piper from Let the Nations Be Glad!, go here. I have never been “into” rap. I am just old enough to have missed the hip-hop scene. But I am a dad of children who love Christ and Christ-centered rap, so I have begun to listen to Christian rap. Lecrae is one of my favorite artists. Yet I would not play Lecrae or Christian rap in a corporate worship service at my church, mostly out of sensitivity to my senior members, not because there is something inherently wrong with the music or lyrics.
