Paul wants to emphasize his summary at the end of the letter to the Galatians--pointing out to them that he is writing in his own hand--not that of a scribe's. He wants to give credibility to his writing and make his point strongly. We are not to live outwardly to gain favor with people--what matters is what we are inside. What counts is that we are a new creation in Christ Jesus, not that we follow legalistic rules.

Paul closes with a message of peace, mercy and grace, and calls the Galatians his brothers. Even though his words are sometimes candid and perhaps harsh, he loves this church and wants so badly for them to walk in the ways of Jesus, not the world.
