'The peace of God, which passeth all understanding, shall keep your hearts and minds through Christ Jesus.'—Phil. iv. 7.

The great Mosque of Constantinople was once a Christian church, dedicated to the Holy Wisdom. Over its western portal may still be read, graven on a brazen plate, the words, 'Come unto Me, all ye that labour and are heavy-laden, and I will give you rest.' For four hundred years noisy crowds have fought, and sorrowed, and fretted, beneath the dim inscription in an unknown tongue; and no eye has looked at it, nor any heart responded. It is but too sad a symbol of the reception which Christ's offers meet amongst men, and—blessed be His name!—its prominence there, though unread and unbelieved, is a symbol of the patient forbearance with which rejected blessings are once and again pressed upon us, and He stretches out His hand though no man regards, and calls though none do hear. My text is Christ's offer of peace. The world offers excitement, Christ promises repose.

I. Mark, then, first, this peace of God.

What is it? What are its elements? Whence does it come? It is of God, as being its Source, or Origin, or Author, or Giver, but it belongs to Him in a yet deeper sense, for Himself is Peace. And in some humble but yet real fashion our restless and anxious hearts may partake in the divine tranquillity, and with a calm repose, kindred with that rest from which it is derived, may enter into His rest.

If that be too high a flight, at all events the peace that may be ours was Christ's, in the perfect and unbroken tranquillity of His perfect Manhood. What, then, are its elements? The peace of God must, first of all, be peace with God. Conscious friendship with Him is indispensable to all true tranquillity. Where that is absent there may be the ignoring of the disturbed relationship; but there will be no peace of heart. The indispensable requisite is 'a conscience like a sea at rest.' Unless we have made sure work of our relationship with God, and know that He and we are friends, there is no real repose possible for us. In the whirl of excitement we may forget, and for a time turn away from, the realities of our relation to Him, and so get such gladness as is possible to a life not rooted in conscious friendship with Him. But such lives will be like some of those sunny islands in the Eastern Pacific, extinct volcanoes, where nature smiles and all things are prodigal and life is easy and luxuriant; but some day the clouds gather, and the earth shakes, and fire pours forth, and the sea boils, and every living thing dies, and darkness and desolation come. You are living, brother, upon a volcano's side, unless the roots of your being are fixed in a God who is your friend.

Again, the peace of God is peace within ourselves. The unrest of human life comes largely from our being torn asunder by contending impulses. Conscience pulls this way, passion that. Desire says, 'Do this'; reason, judgment, prudence say, 'It is at your peril if you do!' One desire fights against another, and so the man is rent asunder. There must be the harmonising of all the Being if there is to be real rest of spirit. No longer must it be like the chaos ere the creative word was spoken, where, in gloom, contending elements strove.

Again, men have not peace, because in most of them everything is topmost that ought to be undermost, and everything undermost that ought to be uppermost. 'Beggars are on horseback' (and we know where they ride), 'and princes walking.' The more regal part of the man's nature is suppressed, and trodden under foot; and the servile parts, which ought to be under firm restraint, and guided by a wise hand, are too often supreme, and wild work comes of that. When you put the captain and the officers, and everybody on board that knows anything about navigation, into irons, and fasten down the hatches on them, and let the crew and the cabin boys take the helm and direct the ship, it is not likely that the voyage will end anywhere but on the rocks. Multitudes are living lives of unrestfulness, simply because they have set the lowest parts of their nature upon the throne, and subordinated the highest to these.

Our unrest comes from yet another source. We have not peace, because we have not found and grasped the true objects for any of our faculties. God is the only possession that brings quiet. The heart hungers until it feeds upon Him. The mind is satisfied with no truth until behind truth it finds a Person who is true. The will is enslaved and wretched until in God it recognises legitimate and absolute authority, which it is blessing to obey. Love puts out its yearnings, like the filaments that gossamer spiders send out into the air, seeking in vain for something to fasten upon, until it touches God, and clings there. There is no rest for a man until he rests in God. The reason why this world is so full of excitement is because it is so empty of peace, and the reason why it is so empty of peace is because it is so void of God. The peace of God brings peace with Him, and peace within. It unites our hearts to fear His name, and draws all the else turbulent and confusedly flowing impulses of the great deep of the spirit after itself, in a tidal wave, as the moon draws the waters of the gathered ocean. The peace of God is peace with Him, and peace within.

I need not, I suppose, do more than say one word about that descriptive clause in my text, It 'passeth understanding.' The understanding is not the faculty by which men lay hold of the peace of God any more than you can see a picture with your ears or hear music with your eyes. To everything its own organ; you cannot weigh truth in a tradesman's scales or measure thought with a yard-stick. Love is not the instrument for apprehending Euclid, nor the brain the instrument for grasping these divine and spiritual gifts. The peace of God transcends the understanding, as well as belongs to another order of things than that about which the understanding is concerned. You must experience it to know it; you must have it in order that you may feel its sweetness. It eludes the grasp of the wisest, though it yields itself to the patient and loving heart.

II. So notice, in the next place, what the peace of God does.
