Galatians 4:12-15

Brethren, I urge you to become like me, for I became like you. You have not injured me at all. You know that because of physical infirmity I preached the gospel to you at the first. And my trial which was in my flesh you did not despise or reject, but you received me as an angel of God, even as Christ Jesus. What then was the blessing you enjoyed? For I bear you witness that, if possible, you would have plucked out your own eyes and given them to me.
