The Ephesians are mostly Gentiles, once cut off from access to God, now they have a way to God through the cross. In the same way, sin cuts people’s access to God but we can have a way to Him through Jesus. We have compassion, love, and grief for the unbeliever, because we are only separated by His grace. Plus, we live as a voice of peace in this world, as we recognize more than anyone the source of hostility (sin) and have the solution (Jesus). Engaging in hostile behavior is not beneficial to the kingdom, of which we are citizens. So, we showcase peace in two ways.
