We left one church (we hadn't joined, but had been attending faithfully for one year) partly due to the music. One couple left our current church this past year over music. So, I thought I would talk about music in the church.
I think the words are the most important part of a song. If the words are not Scriptural, then the song should not be sung - end of story. But there are also songs that aren't unscriptural but are also not church worthy in my opinion. Songs that don't really have a message at all don't make sense to me! They are fine for a concert, but I don't think they should be part of a service.
I also think the instruments accompanying the song should be mellow enough to hear the words. I don't feel strongly that any one instrument shouldn't be allowed, but I feel that certain locations make instruments like the full drum sets unacceptable (small churches, etc).
The Bible does say we should bring a new song unto God, but I don't think we have to sing a new song every week. There is something to be said for singing a song again once you know it. Personally, I think it is easier to worship when I know the words and the melody so I don't have to worry about how to sing the song. But, I also don't want to sing the same songs every single week.
How do you feel about music in a church service?
