19 Oh, my dear children! I feel as if I'm going through labor pains for you again, and they will continue until Christ is fully developed in your lives. 20 I wish I were with you right now so I could change my tone. But at this distance I don't know how else to help you.

The Allegory of Hagar and Sarah

21 Tell me, you who want to live under the law, do you know what the law actually says?

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.
