It is such a danger to puff yourself up and imagine that you’re a brilliant person. It’s like the school bully who imagines himself as the hero because he is the strongest. He can beat anyone up. But everyone else knows that he’s not a hero but a jerk. If he were a real hero, he would defend the weak. He would be lifting them up, using his strength to care for them and protect them, not to bully them.
In the same way, with biblical and theological “knowledge” come the intellectual bullies who seem to know so much and imagine themselves to be so knowledgeable. But Paul is saying that they may be only imagining that they are knowledgeable, because if they really knew, they would use their knowledge not to weaken others but to strengthen them. Not to tear them down but to build people up. That’s what love does.
A good word to those of us who love to study the Bible! We must be ever-vigilant in examining ourselves closely.
