One of the great lessons that we must learn is that God is far more generous than we are. Often, when we are confronted with scarcity, it is the result of our own greed, laziness, unbelief, and so on. When this starts to happen, we clutch at what we have even more, which perpetuates the downward cycle. God is the God of abundance, and the thing that corrupts the resultant affluence is something that we call sin.
