[11] I fear for you, that somehow I have wasted my efforts on you. [12] I plead with you, brothers and sisters, become like me, for I became like you. You did me no wrong. [13] As you know, it was because of an illness that I first preached the gospel to you, [14] and even though my illness was a trial to you, you did not treat me with contempt or scorn. Instead, you welcomed me as if I were an angel of God, as if I were Christ Jesus himself. [15] Where, then, is your blessing of me now? I can testify that, if you could have done so, you would have torn out your eyes and given them to me. [16] Have I now become your enemy by telling you the truth? [17] Those people are zealous to win you over, but for no good. What they want is to alienate you from us, so that you may have zeal for them. [18] It is fine to be zealous, provided the purpose is good, and to be so always, not just when I am with you. [19] My dear children, for whom I am again in the pains of childbirth until Christ is formed in you, [20] how I wish I could be with you now and change my tone, because I am perplexed about you!
