Dedicated to providing guidance in daily living through the power of God's grace as experienced in our union with Christ.

Cast Out the Bondwoman and Her Son


Nevertheless what saith the scripture? Cast out the bondwoman and her son: for the son of the bondwoman shall not be heir with the son of the freewoman. So then, brethren, we are not children of the bondwoman, but of the free.  Galatians 4:30-31

In His efforts to bring the believers in the churches of Galatia back to the life of grace following the influence of false teachers, Paul uses the story of Hagar and Sarah and Ishmael and Isaac.


 In verses 25-26, Paul writes, “… for this Hagar is Mount Sinai in Arabia, and corresponds to Jerusalem which now is, and is in bondage with her children-–but the Jerusalem above is free, which is the mother of us all.


Hagar and Ishmael, her son, were slaves of Abraham. Sarah and Isaac were wife and son of Abraham and were free. Ishmael made fun of Isaac (Genesis 21:8-9) and Sarah saw this take place. She said to Abraham:


“Cast out this bondwoman and her son; for the son of this bondwoman shall not be heir with my son, namely with Isaac.”


Abraham did what Sarah demanded. Paul uses the words of Sarah to tell the Christians in Galatia to cast out the idea of living by the law rather than the life of grace.


Paul’s message to the churches of Galatia is appropriate for believers in our churches today. When we serve the Lord in our own strength and wisdom—doing our best for Jesus, we are engaging in law-living.


All believers are to cast out that approach to the Christian life and replace it with the life of grace by living out our spiritual crucifixion and resurrection.
