I'm not sure that I want to agree.
For one thing, what is "serving God"? Do we really know whether a 'God' even exists? Does 'God' really will us to behave in certain ways? How does one know what God's will supposedly is? How does one avoid extremes in that regard, such as ISIS launching a holy war on all unbelievers?
For another, is money really a bad thing? I think that a plausible argument can be made that money is the glue that makes large scale social cohesion and hence civilization possible.
In paleolithic times, people typically lived in tribal clan groups linked by common ancestry, whether real or mythical. Social cohesion arose from blood ties, from a sense of everyone being family so to speak.
But as agriculture was invented and hunter-gatherer camps grew into early cities, people entered a new situation where they encountered strangers every time they left their homes.
All of us have needs and desires. Few of us can satisfy all of them by ourselves, by our own effort. We need the assistance of other people. But why should other people help us meet our needs when they have unmet needs of their own?
That's the genius of money. We get other people to help us by paying them. And where do we get the ability to pay them? By being of service to others. It's the same principle behind our going to work every day.
That's not a bad thing. It's what made market economies possible, along with large-scale social groups and functional specialization (artisans, craftsmen, scribes) that enabled the rise of civilization.
