When we open the book of Acts, we hear Jesus promise twice in the first few verses to send the Holy Spirit to empower the early disciples as they go to all nations to share the good news of Jesus. As we read further, we see the Holy Spirit at work to break down every barrier — geographical, cultural, racial, economic, political, and social — to make the people who come to Jesus into one new people. Paul reflects on the great grace of God in Ephesians chapters 1-3. In today's verse, he challenges Jesus' followers to make every effort to keep what the Holy Spirit and the grace of God had worked to create: a people united by the Holy Spirit and held together with the bond of peace. He wanted them to "wage peace"! He wanted them to be peacemakers and not just "peacewanters." Making peace can happen only when we allow the Spirit to control our hearts while we earnestly and diligently strive to be united through the Spirit as God's children.
