Paul is making some concluding comments and having finished his argument about legalism, he wants to be practical in terms of helping the Galatians become mature in their churches.

Paul uses strong language to condemn anything that takes away from the power of the gospel which comes from faith in the cross of Jesus Christ alone. He uses the imagery of running a race and baking bread to make his points.

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.

The Gospel and Adoption into God’s Family: Galatians 4:1-7Paul introduces the ideas of adoption and inheritance based on the experience of the Gentile areas he is preaching to. Adopted children could inherit all that belonged to the family. All those blessings are ours in Christ Jesus. We do not need to look back.

Paul continues to explain that the covenant made with Abraham is the foundation of faith whereas the Law of Moses has become obsolete. He explains the importance of the Law to highlight sin that separates us from God. Now all are equal in God’s sight if they have faith in Jesus.

Peter comes to visit the church in Antioch and then surprisingly stops eating meals with Gentiles, as if he is still trying to obey the Old Testament Jewish food laws which kept the Jews separate from the Gentiles. Paul challenges Peter to change his behaviour because the law of Moses is no longer in operation and the Gospel unites Jews and Gentiles

In the light of God’s mercy shown to Jews and Gentiles, we should respond by living our lives wholly committed to God. our behaviour and thinking will change.

In seeking to build up the church, Paul addresses the vulnerability of the church to opposition. As Christians we should rejoice with those who rejoice and mourn with those who mourn. We should not seek to revenge opposition but be kind to those who persecute us.

Paul explains the three dimensional Christian life: the past - justification; the present - access to God’s grace: and the future - eternity with God. Suffering is a part of life but we have the Holy Spirit to enable us

Paul develops his teaching about the power of sin and explains how sin came into the world through Adam and Eve. Only Jesus' sacrifice can break the power of sin. The Law of Moses increased the sense of what sin is.
