There is no doubt that a God that can make bread rain from heaven, should be able to provide financially. However, there is not much evidence, backed by any approval of Jesus or God, that church goers are supposed to support an organized religion. When the Jews gave things to build the first arc of the covenant, they gave freely, to the point that God had to ask them to stop. Most religions, however, conveniently leave that part out. In the first century congregation, since there was no official meeting place, anything they gave, was to support each other and those who dedicated their life to preaching. There is no evidence that this was always in the form of money and that it was somewhat perpetual giving.
