12Brethren, I urge you to become like me, for I became like you. You have not injured me at all. 13You know that because of physical infirmity I preached the gospel to you at the first. 14And 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. 15What 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. 16Have I therefore become your enemy because I tell you the truth? 17They zealously court you, but for no good; yes, they want to exclude you, that you may be zealous for them. 18But it is good to be zealous in a good thing always, and not only when I am present with you. 19My little children, for whom I labor in birth again until Christ is formed in you, 20I would like to be present with you now and to change my tone; for I have doubts about you.

Galatians 4:12-20 NKJV
