St. Paul turns to a text from Genesis that the opponents were attempting to use to lead the Galatians astray. He goes through the account of the two sons of Abraham, Ishmael and Isaac, and proclaims the free salvation that comes from Christ. Those who seek their salvation in works of the law belong to the son of slavery, Ishmael; those who have their salvation through faith in Christ alone belong to the son of freedom, Isaac. Such freedom is not found in circumcision, but in the work that Christ has done for us. St. Paul calls the Galatians away from a return to slavery and to remain in the freedom that is theirs as sons of God.
Rev. Tim Storck, pastor at Good Shepherd Lutheran Church in Chesterfield, MI, joins host Rev. Timothy Appel to study Galatians 4:21-31.
“No Other Gospel” is a series on Sharper Iron that goes through the epistle of Galatians. St. Paul writes an urgent letter to the Galatians lest they forsake the one true Gospel. The apostle calls the Galatians away from the teaching of the Judaizers, because salvation does not come when we add any sort of works to what Jesus has done for us. We are only saved by God’s grace in Christ Jesus.
Sharper Iron, hosted by Rev. Timothy Appel, looks at the text of Holy Scripture both in its broad context and its narrow detail, all for the sake of proclaiming Christ crucified and risen for sinners. Two pastors engage with God’s Word to sharpen not only their own faith and knowledge, but the faith and knowledge of all who listen.

Galatians 4:21-31
Example of Hagar and Sarah
21 Tell me, you who desire to be under the law, do you not listen to the law? 22 For it is written that Abraham had two sons, one by a slave woman and one by a free woman. 23 But the son of the slave was born according to the flesh, while the son of the free woman was born through promise. 24 Now this may be interpreted allegorically: these women are two covenants. One is from Mount Sinai, bearing children for slavery; she is Hagar. 25 Now Hagar is Mount Sinai in Arabia;[a] she corresponds to the present Jerusalem, for she is in slavery with her children. 26 But the Jerusalem above is free, and she is our mother. 27 For it is written,
“Rejoice, O barren one who does not bear;
break forth and cry aloud, you who are not in labor!
For the children of the desolate one will be more
than those of the one who has a husband.”
28 Now you,[b] brothers, like Isaac, are children of promise. 29 But just as at that time he who was born according to the flesh persecuted him who was born according to the Spirit, so also it is now. 30 But what does the Scripture say? “Cast out the slave woman and her son, for the son of the slave woman shall not inherit with the son of the free woman.” 31 So, brothers, we are not children of the slave but of the free woman.
