Humanity's attempts to achieve peace with one another are futile without first achieving peace with God. He emphasizes that before Christ, Gentiles were excluded from God's covenant and promises, being "without hope and without God in the world." However, Christ's sacrifice on the cross abolished the division between Jews and Gentiles, creating "one new man" and reconciling both to God. This reconciliation, achieved through the "blood of Christ," is presented as the sole basis for genuine peace.
