"For though by this time you ought to be teachers, you need someone to teach you again the first principles of the oracles of God; and you have come to need milk and not solid food. For everyone who partakes only of milk is unskilled in the word of righteousness, for he is a babe. But solid food belongs to those who are of full age, that is, those who by reason of use have their senses exercised to discern both good and evil. (Heb. 5:12-14)

Charles Simpson, in Pastoral Renewal, writes: "I met a young man not long ago who dives for exotic fish for aquariums. He said that one of the most popular aquarium fish is the shark. He explained that if you catch a small shark and confine it, it will stay a size proportionate to the aquarium. Sharks can be six inches long yet fully matured. But, if you turn them loose in the ocean, they grow to their normal length of eight feet.

I don't know about you, but in my lifetime, I've seen some of the cutest little six-inch Christians who swim around in their little puddles. They have never grown to maturity because they have never applied themselves.
