I can't remember where I heard that, but here's the full quote; "there is no such thing as Christian music, only Christian lyrics." I like that concept. I am a child of 70's & 80's music... AC/DC, Ozzy, Journey, Billy Squire, Led Zeppelin, etc and I LOVE playing that stuff on guitar - even though I now feel the lyrics have something to be desired. So, am I celebrating "satan's music" when I play the guitar riff to "Hell's Bells", "Crazy Train" or "Sunshine of Your Love"? I'm not sure I'm wise enough to fully answer that, but I do believe that what matters most is the heart of the artist who is playing the music. When I was twelve I thought "You Shook Me All Night Long" was just a great song, I had no idea what it was about. Let's flip this topic for a moment. Are we more energized by modern worship songs because of the music style, their heavy guitars and drums that speak our personal music language? Are we really worshiping in the midst of this loud, upbeat music or are we just having fun? Think about this excerpt from Amos 5:23 and ponder what God is thinking when your mind is more on the music than Him; "Away with the noise of your songs! I will not listen to the music of your harps." God is looking for authentic worship. The next time you are worshiping, ask yourself this question throughout the service... who are you there for, God or yourself?
p.s. - I think the title quote has it wrong. All things are made by God, hence it should read "there is no such thing as secular music, only secular words that take God's music in the wrong direction."
