It's easy to feel comfortable when we have money. These financial prayers are for when we are not so fortunate, when the dire need for money obscures our sense of well-being and spirituality, and even detracts from our appreciation of life.
The key to true abundance is to recognize, and appreciate, how much God has already given us. It is not wrong to ask for sustenance when we need it. God is always willing to hear our prayer. If we open our hearts to recognizing and appreciating all that we already have, instead of seeing only the half-empty glass, God does not turn us away.
