Personally, I wouldn’t touch them with a bargepole because they were not birthed via the Spirit of God. What’s wrong with the old hymns, the words are brilliant they just need, perhaps new tunes, although personally I find them just great as they are and I used to love modern worship songs but not so much now. Even if Jesus is mentioned in Jesus Culture music how do you know that it is the Lord Jesus Christ of Nazareth only unique Son of Almighty God you are singing to and not some other ‘jesus’?
