Paul appeals to the Galatians not to follow the zealous Jewish teachers. He reminds them of their care and honour for him when he was with them even though he was ill. Paul uses the Old testament story of Ishmael and Isaac to illustrate that the Galatians belonged to the new covenant, not the old.

Paul uses several stories form the Old Testament to illustrate God’s choices which divided the nation right from the beginning. God chooses to show mercy to some and also chooses who to use for his purposes.

Paul explains how Abraham is an example of faith for every believer, Jew or Gentile. Justification is by faith is not just a beginning but a continuing process that goes on through life. Circumcision is a symbol - it does not save.
