Sounds like simple coveting to me.
Well in the OT you know what happens to people coveting things that were entrusted to their care and they didn’t do right by it. Just saying.
It's not coveting to point out the obvious and accusing someone of sin just because they are making a valid point to invalidate what they are saying is disingenuous.
There is NOWHERE in the NT that we are promised prosperity and success in our lives for being Christian. That is just appealing to the flesh, the lust of the flesh, the lust of the eyes, and the pride of life.
Can Osteen preach the beset life now to these guys?
I guess they didn't have enough faith, eh?
