What Is a Pearl of Great Price?

In the time of Jesus most people were poor and they may not have a lot of land or own much land but there might be somebody who did have a little more land that you could purchase over time. When people would gather wealth or have any form of wealth they often would try to preserve that coins and they would have like a lock box that they would bury in the ground. How do you put a price tag on knowing what will lead to eternal treasure? How do you value that? There is nothing all combined that this world has to offer us that can compare with the pearl that is beyond price, this pearl of great price that is eternal life,. We don't have to pay for it
