CHRISTIAN QUIETNESS. [1123]

[1123] See also STRENGTH IN QUIETNESS, Isaiah 30:7.

Isaiah 30:15. In quietness and in confidence shall be your strength.

The principle of our text is, that “strength,” safety, success, happiness, is the fruit of self-control and of reliance upon God.

I. It requires little observation to perceive that this is so in outward things (Ecclesiastes 2:11). Look out upon life, and see who, in the long run, are the most successful. Is it the stirring and excitable, those who are most conspicuous in its busy competitions? No: it is for the most part the tranquil and retiring; those who make no display, and have the least reliance upon their own powers. The surest gains and the most certain advancement usually attend those who go on quietly and steadily, without grasping at what is beyond their reach, or wasting their energies in unnecessary exertion. The godly who, when they cannot engage on fair terms in the rivalry of the world, keep aloof from it, preserving peace with men, and exercising faith in God, are provided for, and not unfrequently even raised to conspicuous prosperity. In “quietness and confidence” in God’s providential care “is their strength.”

II. Still more important is the application of this sacred principle to what goes on in the Christian’s soul. We can further the great work of our sanctification only by acting upon it. Excitement and self-dependence can do nothing. The work which has been begun by Divine mercy must be carried out by Divine agency. We are to take heed not to throw any obstacles in the way by our rashness or despondency. If under a feeling of the importance of the work we have to do, we set about doing it in any way of our own, we only invite disappointment, and peril the object we have in view. Only in a dutiful and patient waiting upon God can we obtain a blessing. Not all the will-worship which was ever contrived by human ingenuity can bring us nearer heaven.

III. These words should be our guide in every difficulty and emergency of the spiritual life. They bid us give place to no anxiety or alarm. Those who act upon them cannot be fanatics, nor will they despair. They will not seek what God sees fit to deny, nor even to attain to what is excellent by equivocal means. No real strength is to be got by ferment and agitation. We may not do evil that good may come; we may not distrust God’s power and willingness to help us; we may not seek help from Egypt.
IV. These words should be our guide in view of the changes and excitements of our times. Because of them many are filled with unreasonable fears. But are we to lose our patience and steadfastness because irreligious speculators and worldly religionists are in an uproar? No; let them follow their own course; let us act upon the principle of our text. Truth is safe; the Church is founded upon a rock; nothing can harm it, but our attempting to defend it with carnal weapons. Our weapons are the Word of God and prayer. In the use even of them, we must take heed what spirit we are of, that we use them not in a worldly or angry spirit. Let God do His own work. Let us not venture to step beyond ours. It is not our work to keep the world in order. With the eye of our faith fixed upon Him who with unerring wisdom and omnipotent might controls all the changes and developments of human affairs, let us quietly pursue the duties which He has assigned us, and we shall be safe, and strong, and blessed.—J. G. Dowling, M.A.: Sermons, pp. 55–75.

15 For thus saith the Lord GOD, the Holy One of Israel; In returning and rest shall ye be saved; in quietness and in confidence shall be your strength: and ye would not.
