1. Faith, in general, is defined by the Apostle, elegcos pragmatvn ou blepomenvn. An evidence, a divine evidence and conviction (the word means both) of things not seen; not visible, not perceivable either by sight, or by any other of the external senses. It implies both a supernatural evidence of God, and of the things of God; a kind of spiritual light exhibited to the soul, and a supernatural sight or perception thereof. Accordingly, the Scripture speaks of God's giving sometimes light, sometimes a power of discerning it. So St. Paul: "God, who commanded light to shine out of darkness, hath shined in our hearts, to give us the light of the knowledge of the glory of God in the face of Jesus Christ." And elsewhere the same Apostle speaks of "the eyes of" our "understanding being opened." By this two-fold operation of the Holy Spirit, having the eyes of our soul both opened and enlightened, we see the things which the natural "eye hath not seen, neither the ear heard." We have a prospect of the invisible things of God; we see the spiritual world, which is all round about us, and yet no more discerned by our natural faculties than if it had no being. And we see the eternal world; piercing through the veil which hangs between time and eternity. Clouds and darkness then rest upon it no more, but we already see the glory which shall be revealed.

2. Taking the word in a more particular sense, faith is a divine evidence and conviction not only that "God was in Christ, reconciling the world unto Himself," but also that Christ loved me, and gave Himself for me. It is by this faith (whether we term it the essence, or rather a property thereof) that we receive Christ; that we receive Him in all His offices, as our Prophet, Priest, and King. It is by this that He is "made of God unto us wisdom, and righteousness, and sanctification, and redemption."

3. "But is this the faith of assurance, or faith of adherence?" The Scripture mentions no such distinction. The Apostle says, "There is one faith, and one hope of our calling"; one Christian, saving faith; "as there is one Lord," in whom we believe, and "one God and Father of us all." And it is certain, this faith necessarily implies an assurance (which is here only another word for evidence, it being hard to tell the difference between them) that Christ loved me, and gave Himself for me. For "he that believeth" with the true living faith "hath the witness in himself": "the Spirit witnesseth with his spirit that he is a child of God." "Because he is a son, God hath sent forth the Spirit of His Son into his heart, crying, Abba, Father"; giving him an assurance that he is so, and a childlike confidence in Him. But let it be observed, that, in the very nature of the thing, the assurance goes before the confidence. For a man cannot have a childlike confidence in God till he knows he is a child of God. Therefore, confidence, trust, reliance, adherence, or whatever else it be called, is not the first, as some have supposed, but the second, branch or act of faith.

III. 1. And, first, how are we justified by faith? In what sense is this to be understood? I answer, Faith is the condition, and the only condition, of justification. It is the condition: none is justified but he that believes: without faith no man is justified. And it is the only condition: this alone is sufficient for justification. Every one that believes is justified, whatever else he has or has not. In other words: no man is justified till he believes; every man when he believes is justified.

2. "But does not God command us to repent also? Yea, and to `bring forth fruits meet for repentance'--to cease, for instance, from doing evil, and learn to do well? And is not both the one and the other of the utmost necessity, insomuch that if we willingly neglect either, we cannot reasonably expect to be justified at all? But if this be so, how can it be said that faith is the only condition of justification?" God does undoubtedly command us both to repent, and to bring forth fruits meet for repentance; which if we willingly neglect, we cannot reasonably expect to be justified at all: therefore both repentance, and fruits meet for repentance, are, in some sense, necessary to justification. But they are not necessary in the same sense with faith, nor in the same degree. Not in the same degree; for those fruits are only necessary conditionally; if there be time and opportunity for them. Otherwise a man may be justified without them, as was the thief upon the cross (if we may call him so; for a late writer has discovered that he was no thief, but a very honest and respectable person!); but he cannot be justified without faith; this is impossible. Likewise, let a man have ever so much repentance, or ever so many of the fruits meet for repentance, yet all this does not at all avail; he is not justified till he believes. But the moment he believes, with or without those fruits, yea, with more or less repentance, he is justified. --Not in the same sense; for repentance and its fruits are only remotely necessary; necessary in order to faith; whereas faith is immediately necessary to justification. It remains, that faith is the only condition, which is immediately and proximately necessary to justification.
