There was a fishing vessel in the middle of the ocean fishing for cod. They threw out their net and it caught a great amount of fish. It took quite a while for the net to be raised and brought into the boat. In the net there were many different kinds of fish. The fishermen then began the tedious and patient job of separating the fish. Out of the many different types or species of fish they found a generous amount of cod. They also were able to find other valuable types of fish to sell but many other types were discarded and thrown out. The Kingdom of God is finding the valuable among the many types of things being offered. It is also knowing what to keep and discard.
