2 Peter 1:19

The question, then, is not here, whether the prophets deserve more credit than the gospel; but Peter regarded only this, to shew how much deference the Jews paid to those who counted the prophets as God's faithful ministers, and had been brought up from childhood in their school.

Whereunto ye do well. This passage is, indeed, attended with some more difficulty; for it may be asked, what is the day which Peter mentions? To some it seems to be the clear knowledge of Christ, when men fully acquiesce in the gospel; and the darkness they explain as existing, when they, as yet, hesitate in suspense, and the doctrine of the gospel is not received as indubitable; as though Peter praised those Jews who were searching for Christ in the Law and the Prophets, and were advancing, as by this preceding light towards Christ, the Sun of righteousness, as they were praised by Luke, who, having heard Paul preaching, searched the Scripture to know whether what he said was true. (Acts 17:11)

But in this view there is, first, an inconsistency, because it thus seems that the use of the prophecies is confined to a short time, as though they would be superfluous when the gospel-light is seen. Were one to object and say, that this does not necessarily follow, because until does not always denote the end. To this I say, that in commands it cannot be otherwise taken: “Walk until you finish your course;” “Fight until you conquer.” In such expressions we doubtless see that a certain time is specified. But were I to concede this point, that the reading of the prophets is not thus wholly cast aside; yet every one must see how frigid is this commendation, that the prophets are useful until Christ is revealed to us; for their teaching is necessary to us until the end of life. Secondly, we must bear in mind who they were whom Peter addressed; for he was not instructing the ignorant and novices, who were as yet in the first rudiments; but even those respecting whom he had before testified, that they had obtained the same precious faith, and were confirmed in the present truth. Surely the gross darkness of ignorance could not have been ascribed to such people. I know what some allege, that all had not made the same progress, and that here beginners who were as yet seeking Christ, are admonished.

But as it is evident from the context, that the words were addressed to the same persons, the passage must necessarily be applied to the faithful who had already known Christ, and had become partakers of the true light. I therefore extend this darkness, mentioned by Peter, to the whole course of life, and the day, I consider will then shine on us when we shall see face to face, what we now see through a glass darkly. Christ, the Sun of righteousness, indeed, shines forth in the gospel; but the darkness of death will always, in part, possess our minds, until we shall be brought out of the prison of the flesh, and be translated into heaven. This, then, will be the brightness of day, when no clouds or mists of ignorance shall intercept the bright shining of the Sun.

And doubtless we are so far from a perfect day, as our faith is from perfection. It is, therefore, no wonder that the state of the present life is called darkness, since we are far distant from that knowledge to which the gospel invites us.

In short, Peter reminds us that as long as we sojourn in this world, we have need of the doctrine of the prophets as a guiding light; which being extinguished, we can do nothing else but wander in darkness; for he does not disjoin the prophecies from the gospel, when he teaches us that they shine to shew us the way. His object only was to teach us that the whole course of our life ought to be guided by God's word; for otherwise we must be involved on every side in the darkness of ignorance; and the Lord does not shine on us, except when we take his word as our light.

But he does not use the comparison, light, or lamp, to intimate that the light is small and sparing, but to make these two things to correspond,--that we are without light, and can no more keep on the right way than those who go astray in a dark night; and that the Lord brings a remedy for this evil, when he lights a torch to guide us in the midst of darkness.

What he immediately adds respecting the day star does not however seem altogether suitable to this explanation; for the real knowledge, to which we are advancing through life, cannot be called the beginning of the day. To this I reply, that different parts of the day are compared together, but the whole day in all its parts is set in opposition to that darkness, which would wholly overspread all our faculties, were not the Lord to come to our help by the light of his word.

This is a remarkable passage: we learn from it how God guides us. The Papists have ever and anon in their mouth, that the Church cannot err. Though the word is neglected, they yet imagine that it is guided by the Spirit. But Peter, on the contrary, intimates that all are immersed in darkness who do not attend to the light of the word. Therefore, except thou art resolved wilfully to cast thyself into a labyrinth, especially beware of departing even in the least thing from the rule and direction of the word. Nay, the Church cannot follow God as its guide, except it observes what the word prescribes.

In this passage Peter also condemns all the wisdom of men, in order that we may learn humbly to seek, otherwise than by our own understanding, the true way of knowledge; for without the word nothing is left for men but darkness.

It further deserves to be noticed, that he pronounces on the clearness of Scripture; for what is said would be a false eulogy, were not the Scripture fit and suitable to shew to us with certainty the right way. Whosoever, then, will open his eyes through the obedience of faith, shall by experience know that the Scripture has not been in vain called a light. It is, indeed, obscure to the unbelieving; but they who are given up to destruction are wilfully blind. Execrable, therefore, is the blasphemy of the Papists, who pretend that the light of Scripture does nothing but dazzle the eyes, in order to keep the simple from reading it. But it is no wonder that proud men, inflated with the wind of false confidence, do not see that light with which the Lord favors only little children and the humble. With a similar eulogy David commends the law of God in Psalms 19 and 119.
