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.
