The second verse is in contrast to the one who is “puffed up” about their “knowledge,” “…If anyone supposes that he knows anything he has not yet know as he ought to know…” That one is pretty clear.
This is in the part of the book where Paul is dealing with meat sacrificed to idols. While that is part of his instruction for that issue, this seems to have also a broader application.
We learn in 1 Corinthians 12:7 that the gifts of the Spirit are given for the common good. We are not given gifts or knowledge for our own benefit. No, gifts and knowledge are for the benefit and edification of the Body. Paul addresses this earlier in the book, 1 Corinthians 4:7, all we have, gifts and knowledge is the gift of God. It is His grace. As Paul states in Ephesians 2:8 – 10 that excludes boasting.
So rather than being impressed with ourselves, it seems a better course of action to be good stewards of what God has given us and use our gifts and knowledge to build up those around us in their walk with Christ…
…oh, they are supposed to be doing that for us as well.
