2 Corinthians 1:11-12

11as you also join in helping us by prayer, so that many people may give thanks to God on our behalf for the gracious gift given to us through the help of many.

12For our reason for confidence is this: the testimony of our conscience, that with pure motives and sincerity which are from God – not by human wisdom but by the grace of God – we conducted ourselves in the world, and all the more toward you.
