In Galatians 4:4-5, Paul describes the incarnation event:
But when the set time had fully come, God sent his Son, born of a woman, born under the law, to redeem those under the law, that we might receive adoption to sonship.
The description of the Son as born under the law makes sense to me in context of the letter which deals so much with the law, but why does he also call out the Son as one "born of a woman"? Is this for some reason to stress his humanity? Or the method of the sending? And how does it tie in with any of the rest of the letter if at all?
