There is no obligation on us to be richer, or busier, or more efficient, or more productive, or more progressive, or any way worldlier or wealthier, if it does not make us happier.
God may allow His servant to succeed when He has disciplined him to a point where he does not need to succeed to be happy. The man who is elated by success and is cast down by failure is still a carnal man. At best his fruit will have a worm in it.
