I am afraid on your account that perhaps I have labored for you in vain.
I implore you, brothers, be as I am, because I have also become as you are. You did me no wrong; you know that it was because of a physical illness that I originally preached the gospel to you, and you did not show disdain or contempt because of the trial caused you by my physical condition, but rather you received me as an angel of God, as Christ Jesus. Where now is that blessedness of yours? Indeed, I can testify...
Galatians 4:11–20
