TREASURES OF THE KINGDOM
The last three "Kingdom Parables" in the Gospel of Mathew are a unit tied together. They focus on the Kingdom of God and the Last Judgment. The Kingdom is a treasure for which we should be willing to give up all earthly pursuits and attachments. The promise is that the righteous who inherit eternal life, live forever in the presence of God. They are the ones, who on discovering the Messiah, leave everything worldly behind and follow Christ. Both, the laborer who found the treasure in the field and the merchant who discovered the valuable pearl, had the wisdom to understand what they found and were determined to give up everything worldly. While the Old Testament Scriptures imparted wisdom (Prov 2:1- 4, Is 33:6) the Gospel of Jesus imparts a new form of wisdom in the revelation of God the Son and His gift of eternal life.
The bad and good fish is an imagery of The Last Judgement in which God separates the true believers from the wicked. Just as the net is cast into the sea drawing many fish, the gospel message is spread into the world, drawing many people to it. The net gathers all types of fish, regardless of their value. In the same way, the gospel attracts many people who neither repent nor desire to follow Christ. However, false believers and true Christians are sorted like the good and bad fish at the end of the age.
In the parable of the Householder, Jesus instructs His disciples (and now us) that in order to receive a fuller understanding of the Kingdom of God, His teachings must be studied like the Scribes who use all of Sacred Scriptures like that of a wise householder, who makes use of everything in his storeroom (older items/foodstuffs and newer produce/products) available to him (Mt 5:17; 13:11). Hence, everything should be brought forth from the "storehouse" of God's WORD. The Old and the New Testament scriptures must be studied in light of the revelation of Jesus Christ.
Which character do we represent viz., The Farmer, Merchant or Householder. Do we see ourselves as the good/bad fish?
