Galatians 4:12-20

¹² “I beg of you, brothers and sisters, become as I am, for I also have become as you are. You have done me no wrong; ¹³ but you know that it was because of a bodily illness that I preached the gospel to you the first time; ¹⁴ and you did not despise that which was a trial to you in my bodily condition, nor express contempt, but you received me as an angel of God, as Christ Jesus Himself. ¹⁵ Where then is that sense of blessing you had? For I testify about you that, if possible, you would have torn out your eyes and given them to me. ¹⁶ So have I become your enemy by telling you the truth? ¹⁷ They eagerly seek you, not in a commendable way, but they want to shut you out so that you will seek them. ¹⁸ But it is good always to be eagerly sought in a commendable way, and not only when I am present with you. ¹⁹ My children, with whom I am again in labor until Christ is formed in you— ²⁰ but I could wish to be present with you now and to change my tone of voice, for I am at a loss about you!”

Received me as an angel: Paul was treated well by Galatians during his time of need. This is said in order to remind the church of their past unity with Paul and the Gospel message. When he left, the church decided to switch gears and turn their back on Paul and the Gospel. They chose to listen to false teachers over Paul. 

Again in labor: The Galatians have lost ground with the Gospel. Paul labored before to help form Christ in them, and now he is still having to labor because of their immaturity.
