What does Matthew 13:44 mean?

God's kingdom is like someone who finds a hidden treasure in a field. When he realizes what he's found, he covers it up again, goes home full of joy, and sells everything he owns just so he can buy that field. Matthew 13:44 - Modern Text Bible

(Jesus uses the image of a hidden treasure to show how valuable God's kingdom is. It's worth giving up everything else to have it.)
