the music is important but remember there's is a whole denomination that don't use any instruments in their services. And if you don't go to a church that can pay you 400 or 500 a week then you need to get you a job or get your chops up so you can get a major gig.
i've played, directed, taught songs, and led praise and worship for years for a little of nothing but i look at it as playing for the Lord. We have one of the best praise teams and choirs in my city. I do my best at every service and rehearsal because its for the Lord. God has blessed me with more than those musicians making the 4 and 500 dollars a week. So even if you sacrifice God will bless you.
