In Galatians 6:11-18, Paul emphasizes the importance of the cross of Christ, contrasting it with those who insist on circumcision merely to avoid persecution. He asserts that neither circumcision nor uncircumcision has any value; the only thing that matters is the new creation in Christ. Paul proudly bears the marks of Jesus on his body, which are signs of his suffering and dedication to Christ, dismissing any other requirement. He concludes by blessing those who follow this rule of life in Christ and reaffirming peace and mercy upon them, signing off with a plea for no more interference as he serves Christ.
