(Proverbs 21:20 KJV) There is treasure to be desired and oil in the dwelling of the wise; but a foolish man spendeth it up.
Let me give you a general principle based on observation. Countries that are culturally Christian are wealthier than non-Christian countries. Protestant countries are wealthier than Roman Catholic or Orthodox countries. I don’t know if this is universal. I have not done a scientific study. It is just an observation.
It is not a matter of natural resources. It is not a matter of intelligence. So what is it? It has to do with having a resource pool of wisdom that comes from a fear of the Lord. This is not to say that a majority of these people are believers or practice what they believe. A general acknowledgment of certain values seemed to do the trick.
So? If it applies to cultures then why would it not apply to individuals and families? I am not talking about a get rich scheme. I am talking about a life where your needs are met. It seems to be a fringe benefit of following the Living God.
