1 Corinthians 8:2

8:2 If someone thinks he knows something, he does not yet know to the degree that he needs to know.

1 Corinthians 11:14

11:14 Does not nature¹ itself teach you that if a man has long hair, it is a disgrace for him,

13:4 Love is patient, love is kind, it is not envious. Love does not brag, it is not puffed up.

¹sn Paul does not mean nature in the sense of “the natural world” or “Mother Nature.” It denotes “the way things are” because of God’s design.
