The situation in Galatia is intriguing. Paul was originally detained in Galatia because of an unknown illness (4:13-14), so he took the opportunity to preach to the pagan Gentiles in the region. They received the gospel with joy and faith, and Paul left to continue his missionary journey. Then false teachers, trying to please the Jewish authorities, began to teach the new Gentile Christians in Galatia that they needed to also obey aspects of the Jewish law – such as circumcision and observing the holy days and festivals (4:10).
Paul was outraged! If the Galatian Christians received salvation through faith alone, then they should continue to live by faith alone! Adding requirements to the gospel makes it a false gospel… in essence, it is teaching that we are justified through works – which is impossible!
Paul continues to counter the false teachers by giving examples from the Old Testament that prove that justification has always been by faith and never by works (or the law). In Chapter 3, he pointed back to Abraham’s faith as an example (3:6) and also quoted from Habakkuk 2:4, “The righteous shall live by faith” (3:11). And in today’s reading, Paul contrasts the two sons of Abraham – saying that Ishmael represented slavery under the law, but Isaac was a child of the promise…he represented faith.
And then Paul does something extraordinary… he tells the Gentile Galatians – those who used to worship pagan gods – that they are also children of the promise; consequently, they are not under the law (4:28)! This is amazing! And a truth that should set us free from works-righteousness and help us to embrace the gospel of grace.
But we mustn’t think that God has forsaken those of Jewish heritage. ABSOLUTELY NOT! God has opened the gates of heaven to all who turn to Him in faith!
We see a picture of extraordinary faith in today’s reading from the Old Testament, as Esther, puts her life in God’s hands and acts on behalf of the Jewish people…
Then Esther told them to reply to Mordecai, “Go, gather all the Jews to be found in Susa, and hold a fast on my behalf, and do not eat or drink for three days, night or day. I and my young women will also fast as you do. Then I will go to the king, though it is against the law, and if I perish, I perish” (Esther 4:15-16).
This is the kind of faith that pleases God… a self-sacrificing sort of faith, that surrenders everything into God’s hands. Self-justification through good works is an arrogant affront to God. The love of Christ is what compels us to good deeds because our salvation has been accomplished through his perfect work on the cross! When we add anything to the gospel, it becomes a false gospel!
