Here we have, I. A definition or description of the grace of faith in two parts. 1. It is the substance of things hoped for. Faith and hope go together; and the same things that are the object of our hope are the object of our faith. It is a firm persuasion and expectation that God will perform all that he has promised to us in Christ; and this persuasion is so strong that it gives the soul a kind of possession and present fruition of those things, gives them a subsistence in the soul, by the first-fruits and foretastes of them: so that believers in the exercise of faith are filled with joy unspeakable and full of glory. Christ dwells in the soul by faith, and the soul is filled with the fullness of God, as far as his present measure will admit; he experiences a substantial reality in the objects of faith. 2. It is the evidence of things not seen. Faith demonstrates to the eye of the mind the reality of those things that cannot be discerned by the eye of the body. Faith is the firm assent of the soul to the divine revelation and every part of it, and sets to its seal that God is true. It is a full approbation of all that God has revealed as holy, just, and good; it helps the soul to make application of all to itself with suitable affections and endeavours; and so it is designed to serve the believer instead of sight, and to be to the soul all that the senses are to the body. That faith is but opinion or fancy which does not realize invisible things to the soul, and excite the soul to act agreeably to the nature and importance of them.

II.An account of the honour it reflects upon all those who have lived in the exercise of it (Heb 11:2): By it the elders obtained a good report - the ancient believers, who lived in the first ages of the world. Observe, 1. True faith is an old grace, and has the best plea to antiquity: it is not a new invention, a modern fancy; it is a grace that has been planted in the soul of man ever since the covenant of grace was published in the world; and it has been practiced from the beginning of the revelation; the eldest and best men that ever were in the world were believers. 2. Their faith was their honour; it reflected honour upon them. They were an honour to their faith, and their faith was an honour to them. It put them upon doing the things that were of good report, and God has taken care that a record shall be kept and report made of the excellent things they did in the strength of this grace. The genuine actings of faith will bear to be reported, deserve to be reported, and will, when reported, redound to the honour of true believers.

III.We have here one of the first acts and articles of faith, which has a great influence on all the rest, and which is common to all believers in every age and part of the world, namely, the creation of the worlds by the word of God, not out of pre-existent matter, but out of nothing, Heb 11:3. The grace of faith has a retrospect as well as prospect; it looks not only forward to the end of the world, but back to the beginning of the world. By faith we understand much more of the formation of the world than ever could be understood by the naked eye of natural reason. Faith is not a force upon the understanding, but a friend and a help to it. Now what does faith give us to understand concerning the worlds, that is, the upper, middle, and lower regions of the universe? 1. That these worlds were not eternal, nor did they produce themselves, but they were made by another. 2. That the maker of the worlds is god; he is the maker of all things; and whoever is so must be God. 3. That he made the world with great exactness; it was a framed work, in every thing duly adapted and disposed to answer its end, and to express the perfections of the Creator. 4. That God made the world by his word, that is, by his essential wisdom and eternal Son, and by his active will, saying, Let it be done, and it was done, Psa 33:9. 5. That the world was thus framed out of nothing, out of no pre-existent matter, contrary to the received maxim, that "out of nothing nothing can be made," which, though true of created power, can have no place with God, who can call things that are not as if they were, and command them into being. These things we understand by faith. The Bible gives us the truest and most exact account of the origin of all things, and we are to believe it, and not to wrest or run down the scripture-account of the creation, because it does not suit with some fantastic hypotheses of our own, which has been in some learned but conceited men the first remarkable step towards infidelity, and has led them into many more.

Faith is the substance of things hoped for - Εστι δε πιστις ελπιζομενων ὑποστασις· Faith is the Subsistence of things hoped for; πραγματων ελεγχος ου βλεπομενων· The Demonstration of things not seen. The word ὑποστασις, which we translate substance, signifies subsistence, that which becomes a foundation for another thing to stand on. And ελεγχος signifies such a conviction as is produced in the mind by the demonstration of a problem, after which demonstration no doubt can remain, because we see from it that the thing is; that it cannot but be; and that it cannot be otherwise than as it is, and is proved to be. Such is the faith by which the soul is justified; or rather, such are the effects of justifying faith: on it subsists the peace of God which passeth all understanding; and the love of God is shed abroad in the heart where it lives, by the Holy Ghost. At the same time the Spirit of God witnesses with their spirits who have this faith that their sins are blotted out; and this is as fully manifest to their judgment and conscience as the axioms, "A whole is greater than any of its parts;" "Equal lines and angles, being placed on one another, do not exceed each other;" or as the deduction from prop. 47, book i., Euclid: "The square of the base of a right-angled triangle is equal to the difference of the squares of the other two sides." Ελεγχος is defined by logicians, Demonstratio quae fit argumentis certis et rationibus indubitatis, qua rei certitudo efficitur. "A demonstration of the certainly of a thing by sure arguments and indubitable reasons." Aristotle uses it for a mathematical demonstration, and properly defines it thus: Ελεγχος δε εστις ὁ μη δυνατος αλλως εχειν, αλλ' οὑτως ὡς ἡμεις λεγομεν, "Elenchos, or Demonstration, is that which cannot be otherwise, but is so as we assert." Rhetor. ad Alexand., cap. 14, περι ελεγχου. On this account I have adduced the above theorem from Euclid.

Things hoped for - Are the peace and approbation of God, and those blessings by which the soul is prepared for the kingdom of heaven. A penitent hopes for the pardon of his sins and the favor of his God; faith in Christ puts him in possession of this pardon, and thus the thing that was hoped for is enjoyed by faith. When this is received, a man has the fullest conviction of the truth and reality of all these blessings though unseen by the eye, they are felt by the heart; and the man has no more doubt of God's approbation and his own free pardon, than he has of his being.

In an extended sense the things hoped for are the resurrection of the body, the new heavens and the new earth, the introduction of believers into the heavenly country, and the possession of eternal glory.

The things unseen, as distinguished from the things hoped for, are, in an extended sense, the creation of the world from nothing, the destruction of the world by the deluge, the miraculous conception of Christ, his resurrection from the dead, his ascension to glory, his mediation at the right hand of God, his government of the universe, etc., etc., all which we as firmly believe on the testimony of God's word as if we had seen them. See Macknight. But this faith has particular respect to the being, goodness, providence, grace, and mercy of God, as the subsequent verses sufficiently show.

Now faith is the substance of things hoped for,.... The "faith" here spoken of is not a mere moral virtue, which is a branch of the law; nor a bare assent to anything revealed, declared, and affirmed in the Gospel; nor a faith of doing miracles; nor an implicit one; nor a mere profession of faith, which sometimes is but temporary; nor the word or doctrine of faith; but that which is made mention of in the preceding chapter, by which the just man lives, and which has the salvation of the soul annexed to it: and it does not so much design any particular branch, or act of faith, but as that in general respects the various promises, and blessings of grace; and it chiefly regards the faith of Old Testament saints, though that, as to its nature, object, and acts, is the same with the faith of New Testament ones; and is a firm persuasion of the power, faithfulness, and love of God in Christ, and of interest therein, and in all special blessings: it is described as "the substance of things hoped for"; and which, in general, are things unseen, and as yet not enjoyed; future, and yet to come; difficult to be obtained, though possible, otherwise there would be no hope of them; and which are promised and laid up; and in particular, the things hoped for by Old Testament saints were Christ, and eternal glory and happiness; and by New Testament ones, more grace, perseverance in it, the resurrection of the dead, and eternal life. Now faith is the "substance" of these things; it is the ground and foundation of them, in which there is some standing hope; in which sense the word is used by Septuagint in Psa 69:2. The word of promise is principal ground and foundation of hope; and faith, as leaning on the word, is a less principal ground; it is a confident persuasion, expectation, and assurance of them. The Syriac version renders it, the "certainty" of them; it is the subsistence of them, and what gives them an existence, at least a mental one; so with respect to the faith and hope of the Old Testament saints, the incarnation, sufferings, and death of Christ, his resurrection, ascension, and session at God's right hand, are spoken of, as if they then were; and so are heaven, and glory, and everlasting salvation, with regard to the faith and hope of New Testament saints: yea, faith gives a kind of possession of those things before hand, Joh 6:47. Philo the Jew (e) says much the same thing of faith;

"the only infallible and certain good thing (says he) is, that faith which is faith towards God; it is the solace of life, , "the fulness of good hopes", &c.''

It follows here,

the evidence of things not seen; of things past, of what was done in eternity, in the council and covenant of grace and peace; of what has been in time, in creation, and providence; of the birth, miracles, sufferings, death, resurrection, and ascension of Christ; of things present, the being, perfections, love, &c. of God; of the session of Christ at God's right hand, and his continual intercession; and of the various blessings of grace revealed in the Gospel; and of future ones, as the invisible realities of another world: faith has both certainty and evidence in it.
