Satisfaction in Bulimia?

I just read an interesting blog article called the "Plague of the Privileged" from the Purple Cellar blog.

It was a great blog about hunger, bulimia and trying to find satisfaction apart from God.
I found it was encouraging and helpful to me to keep perspective not on my circumstances so much but on Christ.

In the back of my mind I couldn't help thinking about the prosperity message I recently heard in which the preacher was teaching that the gospel is about my self worth and my living in material abundance. I couldn't help but think that the message was all about what God could do for my portfolio and not about what Christ did on the cross for those who hated & scorned him, and how empty and unsatisfying that message is when hardship and trials come. When I think about it bulimia and seeking satisfaction in material abundance is sort of the same faithless seeking to fill my soul with that which will never truly satisfy.
