Codfish is a big business. The market is huge. When codfish were first being shipped, they froze them. They noticed that the flavor was lost during shipping. Somebody came up with the idea to put them in tanks and ship them in actual seawater. Even then the codfish would arrive at the market 3 or 4 days later, and would have lost much of their flavor because they were not active enough in the tank. They had a kind of mushy texture.
Finally, they learned to ship the codfish with a couple of catfish in the tank with them. The catfish is the natural enemy of codfish. During shipping the catfish would chase the codfish all around the tank the whole time, and when they got to the place where they were going, the codfish tasted like you just pulled them out of the sea. Their texture was great; their taste was even better than before.
See God knows that we are codfish in a catfish world. God allows all things, even catfish type things to help us grow strong and if He kept us from those things, we wouldn't grow into the image of Jesus Christ. Jesus himself said, "In this world you are going to have struggles. You are going to have troubles, tribulations, but be of good courage. I have overcome the world and I am going to take those troubles and I am going to transform you more and more in to my likeness."
