The book of Genesis in the Bible tells the story of Joseph, who, though cast into a pit by his brothers and sold into slavery in Egypt where he spent time in prison, managed to become a powerful official in the Pharaoh's government. Under Joseph's leadership the nation was spared total destruction.
Egypt had entered into a period of great wealth and abundance. But instead of squandering it, as do most of the politicians of today on reckless spending, Joseph initiated a program of savings. A large portion of the fruit of the labors of the Egyptian people was stored away in case of future famine.
And it was an act of Divine providence that led Joseph to implement such a plan.
In a few years the Egyptians suffered through a severe drought and famine that would have normally killed most if not all of its inhabitants. But Joseph had made sure the nation was ready, and the goods and commodities he had stored away saved their lives during the years of famine.
The lessons for us as individuals and as nations abound. He who has ears to hear, let him hear!
