If you got good pay, which I assume you do, and invested it with Gods leading, which most of us do not, I would assume that they would get rich. Then they tithe on their income, which many of us do not, and God blesses them more. They get rich, well that lines up with the Word. They give to the poor, they give offerings as well as tithe, and guess what? God blesses them more. Then God tells this man, buy this property and pay this much. The man obeys, Next thing you know, there is freeway going through, and guess what again? They want his land for a interchange. The man who obeyed God and bought the land now makes a huge profit, some of which he keeps and most of what he gives as offerings....
How can you question the prosperity of a man who follows Gods Word and obeys Gods instructions? Instead, Why don't you do the same? Then people can bad mouth you! Now that sounds like fun.
