Galatians 4:8-16

But then, indeed, when you did not know God, you served those which by nature are not gods. But now after you have known God, or rather are known by God, how is it that you turn again to the weak and beggarly elements, to which you desire again to be in bondage? You observe days and months and seasons and years. I am afraid for you, lest I have labored for you in vain. 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. Have I therefore become your enemy because I tell you the truth?
