Peace is a positive quality of the real man's being; it is an essential element of that kingdom of heaven which is within man, and as such it is perpetual and permanent. Yet peace seems to escape humanity and to hover as a beautiful mirage that is intangible.
In the Old Testament we learn that peace is more than hope or desire; it is a constant and acknowledged promise of God to mankind; and, as with all promises, conditions are involved in its fulfillment. The Psalmist writes (Ps. 119:165), "Great peace have they which love thy law: and nothing shall offend them." The love of God's law brings peace. To love God's law we must obey it; and to obey it we must know what this law is.
In the New Testament we find the record of peace fulfilled, for peace was made manifest in the life of Christ Jesus. It was proved and was established as a constant quality, ever available to those who are obedient to God's commands. Our Master emphasized in practice and teaching the two great commandments, which include all divine law; namely, to love God above all else and to love our neighbor as ourself. Obedience to these commands fulfills for us all God's promise, of peace.
