12For this is our confidence: The testimony of our conscience is that we have conducted ourselves in the world, and especially toward you, with God-given sincerity and purity, not by fleshly wisdom but by God’s grace.13Now we are writing nothing to you other than what you can read and also understand. I hope you will understand completely— 14as you have partially understood us—that we are your reason for pride, as you are ours, in the day of our Lord Jesus.
