If you consider God in the trinity of his persons for a few moments, you will see that in each—Father, Son, and Holy Ghost—the title is apt and correct, "the God of peace."
There is God the everlasting Father, he is the God of peace, for he from all eternity planned the great covenant of peace, whereby he might bring rebels nigh unto him, and make strangers and foreigners fellow-heirs with the saints, and joint-heirs with his Son Christ Jesus. He is the God of peace, for he justifies, and thereby implants peace in the soul, he accepted Christ, and, as the God of peace, he brought him again from the dead; and he ordained peace, peace eternal with his children, through the blood of the everlasting covenant; he is the God of peace.
So is Jesus Christ, the second person, the God of peace for "he is our peace who hath made both one, and hath broken down the middle wall of partition between us." He makes peace between God and man. His blood sprinkled on the fiery wrath of God turned it to love, or rather that which must have broken forth in wrath, though it was love for ever, was allowed to display itself in loving-kindness through the wondrous mediatorship of Jesus Christ; and he is the God of peace because he makes peace in the conscience and in the heart. When he says, "Come unto me all ye that are heavy laden "he gives "rest," and with that rest he gives; the peace of God which passeth all understanding," which keeps our heart and mind. He is moreover the God of peace in the Church, for wherever Jesus Christ dwells, he creates a holy peace. As in the case of Aaron of old, the ointment poured upon the head of Christ trickles down to the very skirts of his garments, and thereby he gives peace,—peace by the fruit of the lips, and peace by the fruit of the heart, unto all them that love Jesus Christ in sincerity.
So is the Holy Ghost the God of peace. He of old brought peace, when chaotic matter yeas in confusion, by the brooding of his wings: he caused order to appear where once there was nothing but darkness and chaos. So in dark chaotic souls he is the God of peace. When winds from the mountains of Sinai, and gusts from the pit of hell sweep across the distressed soul; when, wandering about for rest, our soul fainteth within us, he speaks peace to our troubles, and gives rest to our spirits. When by earthly cares we are tossed about, like the sea-bird, up and down, up and down, from the base of the wave to the billows' crown, he says, "Peace be still." He it is who on the Sabbath-day brings his people into a state of serenity, and bids them enjoy,
"That holy calm, that sweet repose
Which none but he that feels it knows."
Which none but he that feels it knows."
[Charles Spurgeon, The God of Peace; The New Park Street Pulpit, Vol.1]
