Dr. Bill Bright of Campus Crusade for Christ tells this story of a famous oil field called Yates Pool:

During the depression this field was a sheep ranch owned by a man named Yates. Mr. Yates wasn't able to make enough on his ranching operation to pay the principal and interest on the mortgage, so he was in danger of losing his ranch. With little money for clothes or food, his family (like many others) had to live on government subsidy.

Day after day, as he grazed his sheep over those rolling West Texas hills, he was no doubt greatly troubled about how he would pay his bills. Then a seismographic crew from an oil company came into the area and told him there might be oil on his land. They asked permission to drill a wildcat well, and he signed a lease contract.

At 1,115 feet they struck a huge oil reserve. The first well came in at 80,000 barrels a day. Many subsequent wells were more than twice as large. In fact, 30 years after the discovery, a government test of one of the wells showed it still had the potential flow of 125,000 barrels of oil a day.

And Mr. Yates owned it all. The day he purchased the land he had received the oil and mineral rights. Yet, he'd been living on relief. A multimillionaire living in poverty. The problem? He didn't know the oil was there even though he owned it.

Many Christians live in spiritual poverty. They are entitled to the gifts of the Holy Spirit and his energizing power, but they are not aware of their birthright.
