God of peace is one of the names of God that forms part of the closing blessings in a few New Testament books. The greetings and blessings in the letters are a rich source of examples of names for God. Here are two verses that mention the God of peace:
The God of peace shall bruise Satan under your feet shortly. The grace of our Lord Jesus Christ be with you. Amen. (Rom. 16:20 KJV)
Now may the God of peace, who through the blood of the eternal covenant brought back from the dead our Lord Jesus, that great Shepherd of the sheep, equip you . . . (Heb 13:20-21 NIV)
God of Peace is similar to other biblical names of God that tell of the benefits of being in good relationship with Him. Isaiah had prophesied that the Messiah child would share several names of God, one of which would be Prince of peace (Isa. 9:6). In the New Testament He is also called the God of love and peace and the Lord of peace and Paul called Christ “our peace,” though it is not exactly a name of Jesus (Yeshua‘).
In the Old Testament Gideon named an altar Jehovah shalom (or Yahweh shalom), meaning the Lord is Peace (Judg. 6:24).
