What's wrong with CCM?
Simply, it's of the world. CCM does not exalt the Lord Jesus Christ. CCM exalts its 'performers.' CCM promotes the singer and the music, instead of God.
CCM is of the world which is why the world welcomes CCM. Ever notice how CCM is readily accepted by the ungodly? The lost world has never embraced or welcomed the Great Hymns of the Faith.
But they do accept CCM, whether it be "Christian" rock, or "Christian" hip-hop, or "Christian" Rhythm & Blues (R&B). And again, why? Well because CCM is of the world. That is why the world receives and loves CCM.
So called "Christian" rock exalts and elevates the flesh, and not the spirit. Another thing that's wrong with CCM is that CCM artists, a lot of them, sing and perform songs by secular rock groups. (i.e. The band Deliverance has on one of their albums a song ('After Forever') by the wicked and vile rock group Black Sabbath.; 2 Pound Planet sings Bohemian Rhapsody a song by secular group Queen;
DC Talk sings and performs All Apologies by the wicked and blasphemous artist Nirvana.
Furthermore, Rock groups and artists openly admit that their music is ungodly:
"Listen, rock ‘n roll AIN’T CHURCH. It’s nasty business. You gotta be nasty too. If you’re goody, goody, you can’t sing or play it..." (Lita Ford of heavy metal group The Runaways, Los Angeles Times, August 7, 1988).
With her quote, Lita Ford is basically also admitting to the fact that Christianity and Rock and Roll don't mix. You cannot mix them. Even other secular rock artists will admit that.
Newsweek once called Mick Jagger ‘the Lucifer of rock, the unholy roller’ and spoke of ‘his demonic power to affect people.’ (Newsweek, 4 Jan. 1971, quoted in Can we Rock the Gospel, Blanchard, p. 97)
John Lennon:
"I've sold my soul to the DEVIL." (Ray Coleman, Lennon, p.256)
David Bowie:
"Rock has always been THE DEVIL'S MUSIC. . ." (Rolling Stone, Feb. 12, 1976)
"... the whole idea of rock ‘n’ roll is to offend your parents"(Rock drummer King Coffey, The Truth about Rock, p. 30).
To conclude: There is nothing sacred or holy about rock music, whether it is CCM or Secular.
