1 Corinthians 8:1-3
Pride makes those who have it bold and rash. It renders them careless of the feelings of others. It leads them to ridicule and condemn others who do not believe exactly as they do. Pride is an aggressive self-confidence.
There is an old saying: "When people learn a little, they imagine a lot." We remember the tag-end of this saying most frequently: "A little knowledge is a dangerous thing." Thus, proud people, using a little bit of knowledge, are often hair-splitting and hypercritical, setting people against each other, dividing congregations and families. Paul is asking, "Is this love?" No, it is certainly not. He is warning against dependence on simply knowing something, since a person never knows all that he ought to know about a given subject. Such an attitude exhibits a complete dependence on one's self-sufficient knowledge. He is "puffed up."
