Galatians 4: 8-20 (NRSV)

Formerly, when you did not know God, you were enslaved to beings that by nature are not gods. Now, however, that you have come to know God, or rather to be known by God, how can you turn back again to the weak and beggarly elemental spirits? How can you want to be enslaved to them again? You are observing special days, and months, and seasons, and years. I am afraid that my work for you may have been wasted.

You know that it was because of a physical infirmity that I first announced the gospel to you; though my condition put you to the test, you did not scorn or despise me, but welcomed me as an angel of God, as Christ Jesus. What has become of the goodwill you felt? For I testify that, had it been possible, you would have torn out your eyes and given them to me. Have I now become your enemy by telling you the truth? They make much of you, but for no good purpose; they want to exclude you, so that you may make much of them. It is good to be made much of for a good purpose at all times, and not only when I am present with you. My little children, for whom I am again in the pain of childbirth until Christ is formed in you, I wish I were present with you now and could change my tone, for I am perplexed about you
