19 Do you know how I feel right now, and will feel until Christ's life becomes visible in your lives? Like a mother in the pain of childbirth. 20 Oh, I keep wishing that I was with you. Then I wouldn't be reduced to this blunt, letter-writing language out of sheer frustration.

The Allegory of Hagar and Sarah

21 Tell me now, you who have become so enamored with the law: Have you paid close attention to that law?

Matthew Henry's Commentary on Galatians 4:19-21

Commentary on Galatians 4:19-20

(Read Galatians 4:19-20)

The Galatians were ready to account the apostle their enemy, but he assures them he was their friend; he had the feelings of a parent toward them. He was in doubt as to their state, and was anxious to know the result of their present delusions. Nothing is so sure a proof that a sinner has passed into a state of justification, as Christ being formed in him by the renewal of the Holy Spirit; but this cannot be hoped for, while men depend on the law for acceptance with God.

Commentary on Galatians 4:21-27

(Read Galatians 4:21-27)

The difference between believers who rested in Christ only, and those who trusted in the law, is explained by the histories of Isaac and Ishmael. These things are an allegory, wherein, beside the literal and historical sense of the words, the Spirit of God points out something further. Hagar and Sarah were apt emblems of the two different dispensations of the covenant. The heavenly Jerusalem, the true church from above, represented by Sarah, is in a state of freedom, and is the mother of all believers, who are born of the Holy Spirit. They were by regeneration and true faith, made a part of the true seed of Abraham, according to the promise made to him.
