I hope I'm not being redundant but I think we all need to keep I mind that the beauty about gospel music is that it is a musical proclamation of the story of Jesus Christ and who He is. That's doctrine about gospel music it can't be anything else……music that tells the gospel, whether you use Cmaj7 chords, dimished "so-called devil's chord", or a harp, or urban beats that are also used in the hip-hop genre…..the message is what's important. Not the package….the package is used to appeal to the audience so you get their attention, but the focus is Christ no matter how its presented as long as it is biblically true…it's marvelous in God's eyes.
