I was reading the dig deeper part of Matthew 13:44 and found it interesting.

a. The kingdom of heaven is like treasure hidden in a field: The field is the world, but the man does not represent the believer, because we have nothing to buy this treasure with. Instead, Jesus is the man who gave all that He had to buy the field.

i. “Under rabbinic law if a workman came on a treasure in a field and lifted it out, it would belong to his master, the field’s owner; but here the man is careful not to lift the treasure out till he has bought the field.” (Carson)

ii. This parable and the one following are different in character than the previous three. The previous three parables (the wheat and the tares, the mustard seed, and the leaven) each spoke of corruption in the kingdom community. These two parables speak of how highly the King values the people of His kingdom.

b. And for joy over it he goes and sells all that he has and buys that field: The treasure so wonderful that Jesus would give all to purchase is the individual believer. This powerfully shows how Jesus gave everything to redeem the whole world to preserve a treasure in it, and the treasure is His people.

i. “Finding the treasure appears to be by chance. In a land as frequently ravaged as Palestine, many people doubtless buried their treasures; but…to actually find a treasure would happen once in a thousand lifetimes. Thus the extravagance of the parable dramatizes the supreme importance of the kingdom.” (Carson)

ii. “So did Jesus himself, at the utmost cost, buy the world to gain his church, which was the treasure which he desired.” (Spurgeon
