I. The promise. 1. It is universal in its range. It is made to any and every man who will trust in God. 2. It is sure. Men fail for various reasons to keep their promises, but every Divine promise is certain to be fulfilled (H. E. I. 4052, 4053). 3. The peace which is pledged and secured to all who will fulfil the condition of the text is perfect—so perfect that it can only be described by a repetition of the word, “peace, peace.” God never gives in driblets. His gifts are like Himself, perfect for their fulness, for their suitability, for their enduring qualities. God can keep His people in perfect peace when the devil accuses, when the world allures or threatens, when sickness tries, when adversity oppresses, even when the heart is sore tired, and when grim death would affright (H. E. I. 1253, 1893, 1894, 1911–1926; P. D. 2669, 2673).
II. The character described. “Whose mind is stayed on Thee, because he trusted in Thee.” Trust unites. The mind will not be stayed upon God unless there be perfect confidence in His wisdom, power, and love. Trust and love go together. Love begets confidence, and confidence strengthens love. The whole nature must be stayed on God, and on God only. There must be no division in the heart’s affections: we cannot serve God and Mammon and be kept in perfect peace. There must be trust before there can be peace; God Himself cannot give perfect peace to the untrustful.
III. The exhortation. “Trust ye in the Lord for ever.” We trust in the Lord when, encouraged by His promises, we hold fast to Him. It is nothing deeper, nothing more difficult than that. Its very simplicity is its difficulty. As the limpet binds itself to the rock, and is not disturbed by the dashing billows, so let the soul by an ardent affection bind itself to the Rock of Ages. The word “ever” gives a wonderful expansiveness to our text. It points at once to God’s eternity and man’s immortality. He is a being capable of being trusted for ever, and for ever we shall be capable of trusting Him. Our trust is to be unlimited and unintermitted; it is to be exercised at all times, under all circumstances, through all ages.
IV. The stable foundation of the believer’s confidence. “For in the Lord Jehovah is everlasting strength.” The peace must be perfect that rests upon, and rises out of, such a solid foundation. The mountains are “everlasting” only in figure, but the foundation on which we rest is everlasting in fact (Ps. xci. 1, 2).—W. Burrows, B.A.
The world needs the message contained in our text. Most faces that we see are careworn. They are so because behind them there are anxious hearts distressed by fears of various kinds—by fears concerning the body, by fears concerning the soul. The vast majority of men are destitute of true peace; for while in the world there are many ways—of pleasure, of sin, of disappointment, of misery, of death—there is no way of peace. The multitudes who throng past us are miserable because the way of peace they have not known.
I. Look at the person who is kept in peace. He is a person whose mind is stayed on God. A man’s self, sin, pleasure, false religion, vain hopes, are every one of them troubled waves in an ocean of disquietude, and no soul can stay itself on them, though many souls have sought to do so. Who, lying down in the very midst of the sea, can find there repose? As he lieth down upon the waves, they yield beneath him—the billows roll over him; he is sinking in the mighty deep. So with the sinner lying down in the midst of the sea and of the storm of this world apart from God. But he who lieth down upon God is as a man upon a rock, or as one in a mighty fortress; he is at peace—secure in fact and in feeling. But it is only as God is revealed to us in Christ that we may rest upon Him. Apart from Christ, He is to sinners “a consuming fire.” Only through Christ may we find the blessedness we so much need, but through Christ we may find it.
II. Look at the power which keeps the believer in peace. It is not the power of his own faith (H. E. I. 1970, 1975). It is not the power of his own effort, struggling to obtain confidence. It is the power of God: “Thou wilt keep him,” &c. The sinner obtains peace by yielding himself to God (Rom. vi. 13). The believer has peace while he leaves himself in God’s hands, quietly submissive, cheerfully willing that God should lead him and do with him whatever is pleasing in His sight (P. D. 2966–2968, 2970–2972). Then all God’s attributes—His omniscience, His omnipotence, His faithfulness, His tender mercy—minister to his peace (P. D. 3379).
III. Look at the peace in which such a person is kept. It is “perfect peace.” Peace in spite of all that conscience may say, of the temptations that assail us, of the troubles of life, of the certainty and mystery of death. With the peace of pardon, all this peace flows into the soul, increasing more and more. It is the peace of Christ, the same peace which filled and sustained Him (John xiv. 27). You remember that we are shown Him with His head on a pillow, His eyes closed, His mind in unconscious repose, asleep in the midst of the wild storm at night upon the Lake of Galilee, when the waves beat upon the trembling vessel, and the wind strove to raise the waves still higher, and engulph them all. He slept, secure and peaceful, amid the storm. So does the soul of the believer that stayeth itself upon God. Upon what lay that peaceful head of Jesus but upon the unseen arm and heart of God. Men said of Christ mockingly, “He trusted in God.” He did trust in God, as the most exalted believer, and far more than the most exalted believer; and in that simplicity of faith He was kept in peace, sleeping amidst the storm. So is it with the believer. O believer! is it so with you?—Henry Grattan Guinness: Sermon in The Christian World, 1860.
Here is the secret of life—peace, perfect peace—and the sure way of attaining it. Consider—
I. The character contemplated. “Whose mind is stayed on Thee.” His mind is fixed with such intensity that it cannot be diverted from the object on which it is set. This object is not himself (Prov. xxviii. 26), nor his riches (Prov. xxiii. 5), nor his fellow-men (Ch. ii. 22; Jer. xvii. 4, 5), but God, in whom he trusts unhesitatingly, exclusively, universally. He accepts all that the Scriptures reveal concerning God, and makes these revelations the foundation of his confidence and his prayers.
