Treasure in the field

“The kingdom of heaven is like treasure hidden in a field. When a man found it, he hid it again, and then in his joy went and sold all he had and bought that field.” Matthew 13:44
This parable of Jesus is often misunderstood. A common interpretation (since Jesus does not explain this parable in the Scriptures) is that Jesus is the treasure and we must give up all to find Him. But this does not fit with the idiomatic usage of the different elements of the parable, used in all the other parables.
In Matt. 13:37, Jesus says that He is the man who sowed the seed. It stands to reason then, that he is the man in this parable also. In Matt. 13:38, He says that the field represents the world. In Heb. 12:2 we read, “Let us fix our eyes on Jesus, the author and perfecter of our faith, who for the joy set before Him endured the cross, scorning its shame, and sat down at the right hand of the throne of God.”
So we have Jesus as the man, finding treasure in the field, the world. He sold all He had to buy the field, because of the treasure in it. At the cross, He did indeed give up everything to purchase salvation for whoever would come. We are the treasure in the field, that He gave everything for!
