Galatians 4:1-7 ”Not a slave, but a son”

Paul writes to the Galatians who are facing the temptations of legalism.   The law is merely a schoolmaster to bring one to Christ.  The "Christmas" story is about God sending forth His Son, born of a woman, born under the law, to redeem those under the law.  Furthermore, God wasn't just looking for servants, but sons!
