Paul reminds us that we were once far from God - separated, without hope, living in hostility towards one another. But through Jesus, those barriers have been torn down. Christ Himself is our peace, reconciling us to God and breaking down the barriers that divide people. This passage reveals the power of the gospel to unite people from every background, making us fellow citizens and members of God’s household. Once outsiders, we are now built together as a dwelling place for God’s own Spirit.
