I used to listen to rock music of any kind before from deep purple,black sabbath, nazareth, montley crue, kiss, led zeppelin,metallica, queen, skidrow, bon jovi, pantera, slayer,guns & roses, acdc, outfield, scorpion and etc...but things change when I got born again, i stop listening all of these stuffs, I preferred christian rock and metal instead namely; petra, nouveaux, stryper, audio adrenaline, angelica and etc....But as the days gone by in my daily walk with God, i became aware that in listening christian rock was like listening to secular rock, kind of like same old things, it's almost encourage me to listen back again to secular rock. I realized that rock(both christian rock and secular one) are not really for us as believers. So I completely stopped listening both. I prefer praise and worship without screaming and rock metal involved.
As believers , we are not here to be conformed of the pattern of this world. Imagine, how's the church could look like if using METAL tune during worship hour. It's really chaos !!! It's like being in the strip bar or in the rock concert where bunch of hippies, drug addicts , stubborn unbelievers and stuffs are present. Rock metal encourage the flesh, not the spirit, God said worship Him in spirit.
Christian rock are intended FOR unbelievers during crusade and for preaching the gospel. It can draw unbelievers to listen to the crusade. That's the reason Why God allows it in christian community. Using rock and playing it in the church in praise and worship and in your home aren't the same issues, That's very ridiculous !! When you grow older spiritually, you will realize that you don't need all these things.
