“With regard to food sacrificed to idols, we know that ‘we all have knowledge.’ Knowledge puffs up, but love builds up.”
1 Corinthians 8.1
Some Corinthians gloried in their knowledge. Their worldly perspective caused them to ignore or despise others who were not as advanced as they thought they were.
Without love, people exalt themselves because of knowledge. See Jeremiah 9.23-24. Here applies the old phrase that it’s not what, but who, you know.
