Verse 7. 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 wants, 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," Isa 26:3. See Barnes "Joh 14:27".

Which passeth all understanding. That is, which surpasses all that men 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 Barnes "Eph 3:19"; comp. Joh 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. Comp. Isa 26:3,4,20; 37:1-7.

The word here rendered 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.
