“If someone thinks he knows something, he does not yet know to the degree that he needs to know.”
1 Corinthians 8.2
The Corinthians valued knowledge above all things. Their supposed knowledge led to pride, v. 1. What matters is not what we know, but who knows us, v. 3.
We know what we are permitted to know, Dt 29.29. That knowledge we must know, for it is our salvation, in Christ. All else calls for humility.
