Ephesians 2:17 says that "He preached peace to you who were far off and to those who were near." Who is he? Scroll up a few verses and see that the preacher of peace is none other than Christ himself. King Jesus Christ, who has all authority in heaven and on earth, went out of his way to preach to us who were hostile to him. But verse 14 says that he broke down that dividing wall to waive the banner of peace. He could have pressed his thumb on our heads and squashed us like bugs but God, being rich in mercy, made us fellow citizen of heaven.
Praise God for peace with him.
