Have I now become your enemy by telling you the truth?
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.
It is fine to be zealous, provided the purpose is good, and to be so always, not just when I am with you.
My dear children, for whom I am again in the pains of childbirth until Christ is formed in you,
how I wish I could be with you now and change my tone, because I am perplexed about you!
Tell me, you who want to be under the law, are you not aware of what the law says?
For it is written that Abraham had two sons, one by the slave woman and the other by the free woman.
His son by the slave woman was born according to the flesh, but his son by the free woman was born as the result of a divine promise.
These things are being taken figuratively: The women represent two covenants. One covenant is from Mount Sinai and bears children who are to be slaves: This is Hagar.
Now Hagar stands for Mount Sinai in Arabia and corresponds to the present city of Jerusalem, because she is in slavery with her children.
But the Jerusalem that is above is free, and she is our mother.
