Philippians 4:7

And the peace of God which passeth all understanding
Not that peace which God calls his people to among themselves in their effectual calling; and which he requires of them to cultivate and maintain; and which he encourages in them by the promise of his gracious presence among them; and which indeed he is the author of, and therefore is so called, ( Colossians 3:15 ) ; and which may be said to surpass or exceed all speculative knowledge, and understanding; for the one puffs up and profits nothing, but the other edifies; and much less that peace which God has in himself, who is all peace and love, and which passes all understanding, human and angelic; but either that peace which is made with God by the blood of Christ, and is published in the Gospel of peace, which passes and surprises all understanding of men and angels, that it should be; that the thoughts of God should be concerning it from everlasting; that a council of peace should be called and held between the eternal Three, and a covenant of peace entered into; that Christ should be appointed the peace maker, and the chastisement of it laid on him; that he should make it by the blood of his cross, and for men, while enemies to God and to himself: or else that peace of conscience, which arises from a view of peace made by Christ; of justification by his righteousness, and atonement by his sacrifice; and which may be called "the peace of Christ", as the Alexandrian copy reads; both because it is founded upon, and springs from him, and is what he is the donor of: and this is what passes the understanding of every natural man; he knows nothing of this peace, what this tranquillity of mind means; he intermeddles not with this joy; it is unaccountable to him how it should be, that such then should have peace, who have so much trouble, are so much reproached, afflicted, and persecuted, and yet have peace in Christ, while they have tribulation in the world; which shall keep your hearts and minds through Jesus Christ,
or "in Christ Jesus": some read these words prayer wise, or as a wish, "let it", or "may it keep", so the Vulgate Latin; but they are rather a promise, encouraging the saints to the discharge of the above duties; as rejoicing always in the Lord, showing their moderation to all men, avoiding anxious care, and betaking themselves at all times, on all occasions, to prayer to God; in which way they may expect peace, and such as will be of that see vice to them, as here expressed; that is, be a means of their final perseverance; for the peace of God, in either sense, is a preservation of the saints: peace made with God secures them in Christ from all condemnation by the law, sin, Satan, the world, or their own hearts; and peace in their own souls, on so good a foundation as it is, keeps them through Christ as in a garrison, from being overset with the troubles of the world, or the temptations of Satan; and is a means of preserving them from being carried away with the errors and heresies of the wicked, having a witness to truth within themselves; and from every evil way and work, from profaneness and immorality; the grace of God teaching them, and the love of Christ constraining them, which is shed abroad in their hearts, to live and act otherwise.
