A very good christian friend of mine was expected to live like this. He's a sound engineer and at the time did a lot of work for some sort of modern church that specialised in singing and performance. They man who 'ran' this church claimed to live by faith, in that he had faith in the lord to provide him with what he needed. Considering the man had no paid work, the lord provided him with quite a lot - new car, nice house, decent meals, nice hotel rooms whenever they stayed away etc etc.
My friend, a single man, gave his time freely as and when he wasn't earning a conventional living - which he needed in order to pay his bills and run his house. However, this church man was expecting him to do more and more without payment. Then my husband took a phone message for my friend. It was this man wanting him to do a job, and my husband told him, truthfully, that friend wouldn't be able to do it as he knew he'd be working for us on that date and couldn't be expected to give up a paid job (it's not the sort of industry that gives a salaried job). The man said he didn't see why, because he relied on the lord and he always survived.
Anyways, my friend slowly began to see where this church man was trying to lead him, especially when he suggested that friend sell his house because he hardly spent any time there, and donate some of the proceeds to the church.
All I'm saying is, be careful and make sure you know exactly what's expected of you before you leap. No realistic church will ask you to risk your own stability of life for it. If they do, then I question their motives.
