2 Corinthians 1:11-12

11as you help us by your prayers. Then many will give thanks on our behalf for the gracious favor granted us in answer to the prayers of many.

12Now this is our boast: Our conscience testifies that we have conducted ourselves in the world, and especially in our relations with you, with integrity and godly sincerity. We have done so, relying not on worldly wisdom but on God’s grace.
