"...Satan is using music to tear churches apart..."
You are absolutely correct.
I tend to be a touch cynical about it because I have so many colleagues who have lost long time music positions through false accusations and deceit, as I did (rather than honestly being told 'We want someone different in this job who will make us more popular'), and it makes me seriously wonder who is leading this movement in our churches.
IMO, there is something sinister at work here, because if God were really in this, people's lives wouldn't be being destroyed because of it.
To tell you the truth, annie....I would never work in 90% of today's churches because I actually believe the music ministry is to allow Christians to worship (with heart and soul and MIND) and not to draw a crowd or give people warm fuzzies with no meaning, and that's not the trend in today's churches.
I praise the Lord that we found a rare church with the depth to want true Biblical worship, and not popularity.
