I think that this is a fairly loaded question and one in which complexities arise. It seems to me that regardless of religious faith or form of worship, the question's binary opposition would be, to some extent, challenged. I don't think that religious worship forces a choice between prayer and working. If done with an open heart towards the divine, both can be seen as forms of worship. To a great extent, I think that religious figures would argue that both are extensions of one's worship. When we pray, we seek to form a connection with the divine. When we work, we are doing what, for reasons that we might not fully comprehend, the divine has in store for us. I don't see this as a fundamental choice. Yet, I think that both are needed for healthy forms of worship, regardless of denomination. The idea of being productive in any setting and being able to contribute something is part of what many religious faiths teach their followers. At the same time, there has to be some notion of worship in terms of forming the realm of communication with the divine, as to what prayer offers. In this, both are seen as important in the life of the worshipper of the divine.
