Paul speaks to the incredible truth that the Gospel breaks down all barriers, bringing people of every background into one family through Christ. The mystery revealed to Paul was that Gentiles are now fellow heirs and part of the same body as Jews. This unity in Christ isn’t based on who we are or where we come from, but on God’s grace. As believers, we are all called to share this message with others, showing that the Gospel is for everyone, and how through it, we are all united in Christ.
