Check out this article written by Kevin DeYoung about immature knowledgeable Christians and mature ignorant Christians. It is both humorous and informative. Here is a sample
A theologically astute, immature Christian is like a five year old flying an Apache helicopter. Here’s this massive weapon; it can destroy arguments and defend against heresy. It can soar to the heavens and take in glorious sights no one at sea-level will ever witness. This theological helicopter is good for search and rescue, just as good for seek and destroy. Every congregational army would be thrilled with such a vehicle. It’s fast. It’s furious. It’s impressive. But it’s also dangerous. And with a five-year old behind the wheel (or whatever they have in choppers), some people are going to get hurt. It’s not wrong for a little kid to have a helicopter, but it would be nice if he grew up and took some flying lessons before taking the thing out for a spin.
On the other hand, a mature Christian content with the barest theological knowledge is like a 45-year old riding a tricycle. If I had to choose, I’d go with the trike-riding middle-aged man, but only because he’s a little safer than the five-year old fighter pilot. In a perfect world, the 45-year old would learn to ride something for grown-ups. Sure he can get around on the tricycle. But he can’t go very fast or very far. He’s limited in terms of what he can see and experience. He can’t do much to beat back enemies or scale new heights. He’s steady, but not the best he can be.
