Jehovah-shalom: the Lord our peace. The theme presented by this text is the peace which the gospel brings. It is a great mercy to have the gospel of peace, but it is a far greater mercy to have the peace of the gospel.
The nature of this peace was arranged for in the far-back ages of eternity, when the stupendous plan of our redemption in Christ Jesus was determined upon. The foundation of this peace rests on the atoning work of Christ.
To have this peace is to have our wills moving in harmony with the Divine will; it is to have our affections subordinated and controlled by the holy law of God; it is to have our desires elevated—our fears of trouble and death subdued—and our hopes of immortality strong, and bright, and abiding.Commentary taken from The Biblical Illustrator
