1 Corinthians 2:1, 2, 16

And so it was with me, brothers and sisters. When I came to you, I did not come with eloquence or human wisdom as I proclaimed to you the testimony about God.

For I resolved to know nothing while I was with you except Jesus Christ and him crucified.

for, “Who has known the mind of the Lord so as to instruct him?” But we have the mind of Christ.
