Adding anything to the Gospel nullifies it because this nullifies God’s grace.

The apostle Paul says that he wrote this conclusion with large letters. This was likely because he wanted to emphasize the message of grace. The Gospel is no longer ‘good news’ if our works are added as a requirement for forgiveness. A common one of these in Paul’s day was circumcision. The believers from a Jewish background were saying that the Gentile believers had to be circumcised if they were truly God’s people.

Paul rejected this by saying that even the Jewish believers could not keep God’s law perfectly so they were in no position to be boasting about their circumcision. He says “May I never boast except in the cross of our Lord Jesus Christ through which the world has been crucified to me, and I to the world” (Gal 6:14 NIV). He then draws their attention to what really counts … having become a new creation through believing In what Jesus has done for them.

He concludes the letter by drawing their attention to the reality of his sufferings for the Gospel which validate the authority he has for writing this letter to them. Finally he mentions grace in order to remind them that it is through what Jesus has done that they have become God’s people and he calls them brothers and sisters in what should be taken as a call for unity in the church.
