Philippians 4:7

And the peace of God - That harmonizing of all passions and appetites which is produced by the Holy Spirit, and arises from a sense of pardon and the favor of God;

Shall keep your hearts - Φρουρησει· Shall keep them as in a strong place or castle. Your hearts - the seat of all your affections and passions, and minds - your understanding, judgment, and conscience through Christ Jesus; by whom ye were brought into this state of favor, through whom ye are preserved in it, and in whom ye possess it; for Christ keeps that heart in peace in which he dwells and rules. This peace passeth all understanding; it is of a very different nature from all that can arise from human occurrences; it is a peace which Christ has purchased, and which God dispenses; it is felt by all the truly godly, but can be explained by none; it is communion with the Father, and his Son Jesus Christ, by the power and influence of the Holy Ghost.

And the peace of God - The peace which God gives. The peace here particularly referred to is that which is felt when we have no anxious care about the supply of our needs, and when we go confidently and commit everything into the hands of God. "Thou wilt keep him in perfect peace whose mind is stayed on thee;" Isaiah 26:3; see the notes at John 14:27.

Which passeth all understanding - That is, which surpasses all that people had conceived or imagined. The expression is one that denotes that the peace imparted is of the highest possible kind. The apostle Paul frequently used terms which had somewhat of a hyperbolical cast (see the notes on Ephesians 3:19; compare John 21:25, and the language here is that which one would use who designed to speak of that which was of the highest order. The Christian, committing his way to God, and feeling that he will order all things aright, has a peace which is nowhere else known. Nothing else will furnish it but religion. No confidence that a man can have in his own powers; no reliance which he can repose on his own plans or on the promises or fidelity of his fellow-men, and no calculations which he can make on the course of events, can impart such peace to the soul as simple confidence in God.

Shall keep your hearts and minds - That is, shall keep them from anxiety and agitation. The idea is, that by thus making our requests known to God, and going to him in view of all our trials and wants, the mind would be preserved from distressing anxiety. The way to find peace, and to have the heart kept from trouble, is thus to go and spread out all before the Lord; compare Isaiah 26:3-4, Isaiah 26:20; Isaiah 37:1-7. The word rendered here "shall keep," is a military term, and means that the mind would be guarded as a camp or castle is. It would be preserved from the intrusion of anxious fears and alarms.

Through Christ Jesus - By his agency, or intervention. It is only in him that the mind can be preserved in peace. It is not by mere confidence in God, or by mere prayer, but it is by confidence in God as he is revealed through the Redeemer, and by faith in him. Paul never lost sight of the truth that all the security and happiness of a believer were to be traced to the Saviour.

4:7 And the peace of God - That calm, heavenly repose, that tranquility of spirit, which God only can give. Which surpasseth all understanding - Which none can comprehend, save he that receiveth it. Shall keep - Shall guard, as a garrison does a city. Your hearts - Your affections. Your minds - Your understandings, and all the various workings of them; through the Spirit and power of Christ Jesus, in the knowledge and love of God. Without a guard set on these likewise, the purity and vigour of our affections cannot long be preserved.
