True, Stryper's song is an 80s song and surely the devil would use newer, updated styles to enhance his influence... but then, why wouldn't God? A good example of updated Christian rock/metal is here:
Disciple
Do we really think the devil would want to glorify God using this supposedly devilish music? I think he's smarter than that. Our job as Christians is to monitor the lyrics to make sure bad stuff isn't entering our brains.
Below is a list of some music I've purchase in the past that helped me draw closer to God, even if it is of the heavy metal/rock genre. Click on any image for more information.
A personal favorite; Theocracy. These are their CDs:
They also did a self titled CD (my favorite) that's sold out on Amazon.com.
Another favorite, one that took me out of the 80s; Disciple.
You can find there music here:
(And many MANY more)
I could go on but this is a good start for now. Please share with me non-traditional music you've found to bring you closer to God. When time permits, I'll list more traditional church-approved stuff that I liked.
