This was the dying bequest of Christ: "Peace I leave with you, my peace I give unto you: not as the world giveth give I unto you:" and therein lies one of the greatest truths of the blessed and eternal character of Christianity, that it applies to, and satisfies the very deepest want and craving of our nature. The deepest want of man is not a desire for happiness, but a craving for peace; not a wish for the gratification of every desire, but a craving for the repose of acquiescence in the will of God; and it is this which Christianity promises. Christianity does not promise happiness, but it does promise peace. "In the world ye shall have tribulation," saith our Master, "but be of good cheer; I have overcome the world." Now, let us look more closely, into this peace.
The first thing we see respecting it is, that it is called God's peace. God is rest: the infinite nature of God is infinite repose. The "_I am_" of God is contrasted with the _I am become_ of all other things. Everything else is in a state of _becoming_, God is in a state of _Being_. The acorn has become the plant, and the plant has become the oak. The child has become the man, and the man has become good, or wise, or whatever else it may be. God ever _is_; and I pray you once more to observe, that this peace of God, this eternal rest in the Almighty Being, arises out of His unity. Not because He is an unit, but because He is an unity. There is no discord between the powers and attributes of the mind of God; there is no discord between His justice and His love; there is no discord demanding some miserable expedient to unite them together, such as some theologians imagined when they described the sacrifice and atonement of our Redeemer by saying, it is the clever expedient whereby God reconciles His justice with His love. God's justice and love are one. Infinite justice must be infinite love. Justice is but another sign of love. The infinite rest of the "_I am_" of God arises out of the harmony of His attributes.
The next thing we observe respecting this divine peace which has come down to man on earth is, that it is a _living peace_. Brethren, let us distinguish. There are several things called peace which are by no means divine or Godlike peace. There is peace, for example, in the man who lives for and enjoys self, with no nobler aspiration goading him on to make him feel the rest of God; that is peace, but that is merely the peace of toil. There is rest on the surface of the caverned lake, which no wind can stir; but that is the peace of stagnation. There is peace amongst the stones which have fallen and rolled down the mountain's side, and lie there quietly at rest; but that is the peace of inanity. There is peace in the hearts of enemies who lie together, side by side, in the same trench of the battle-field, the animosities of their souls silenced at length, and their hands no longer clenched in deadly enmity against each other; but that is the peace of death. If our peace be but the peace of the sensualist satisfying pleasure, if it be but the peace of mental torpor and inaction, the peace of apathy, or the peace of the soul dead in trespasses and sins, we may whisper to ourselves, "Peace, peace," but there will be no peace; _there_ is not the peace of unity nor the peace of God, for the peace of God is the living peace of love.
