2 Corinthians 1:12

Now this is our boast: Our conscience testifies that we have conducted ourselves in the world, and especially in our relations with you, in the holiness and sincerity that are from God. We have done so not according to worldly wisdom but according to God's grace.

(v12, NIV)

This makes me think back to first Corinthians.

Therefore, as it is written: "Let him who boasts boast in the Lord."

(1 Corinthians 1:31, NIV)

Actually, I prefer the ESV translation of verse 12.

For our boast is this, the testimony of our conscience, that we behaved in the world with simplicity and godly sincerity, not by earthly wisdom but by the grace of God, and supremely so toward you.

(v12, ESV)

The main reasons why I think back to first Corinthians is because of "boast" and "wisdom". The verse I brought up tells us to boast in the Lord. That section was talking about the foolishness of God being wiser than men.

For the foolishness of God is wiser than man's wisdom, and the weakness of God is stronger than man's strength.

(1 Corinthians 1:25, NIV)

First Corinthians also talks about the wisdom of God compared to the wisdom of man. Clearly we know which one is better. However, in this verse refers to the grace of God as opposed to earthly wisdom. Though we learn in 1 Corinthians about choosing God's wisdom over man's wisdom, here the grace of God is by which they behave. Grace also brings a calming and comforting sense to mind.

For it is by grace you have been saved, through faith—and this not from yourselves, it is the gift of God— not by works, so that no one can boast.

(Ephesians 2:8-9, NIV)

When we live in Grace, it is the saving power of the cross that comes to mind. This is why we live the way we live. This is God's grace. And only because of it we can behave in such a way towards others.

We should live relying on God's grace. By him and all he does we can live and move and have our being.
