1 Corinthians 8:2 in the World English Bible
But if anyone thinks that he knows anything, he doesn’t yet know as he ought to know.
Context
1 Now as touching things offered unto idols, we know that we all have knowledge. Knowledge puffeth up, but charity edifieth.
2 And if any man think that he knoweth any thing, he knoweth nothing yet as he ought to know.
3 But if any man love God, the same is known of him.
