"For our boasting is this:the testimony of our conscience that we conducted ourselves in the world in simplicity and godly sincerity, not with fleshly wisdom but by the grace of God, and more abundantly toward you."
"Great is my boldness of speech toward you, great is my boasting on your behalf. I am filled with comfort. I am exceedingly joyful in all our tribulation."
"Therefore show to them, and before the churches, the proof of your love and of our boasting on your behalf."
"As the truth of Christ is in me, no one shall stop me from this boasting in the regions of Achaia."
