John 5:39

Wherefore Christ when He referred the Jews to the Scriptures, sent them not to a mere reading, but a careful and considerate search; for He said not, "Read the Scriptures," but, "Search the Scriptures." Since the sayings relating to Him required great attention, (for they had been concealed from the beginning for the advantage of the men of that time,) He biddeth them now dig down with care that they might be able to discover what lay in the depth below. These sayings were not on the surface, nor were they cast forth to open view, but lay like some treasure hidden very deep. Now he that searcheth for hidden things, except he seek them with care and toil, will never find the object of his search. For which cause He said, "Search the Scriptures, because in them ye think ye have eternal life." He said not, "Ye have," but "ye think," showing that they gained from them nothing great or high, expecting as they did to be saved by the mere reading, without the addition of faith. What He saith therefore is of this kind: "Do ye not admire the Scriptures, do ye not think that they are the causes of all life? By these I confirm My claims now, for they are they which testify of Me, yet ye will not come to Me that ye may have eternal life." It was thus with good reason that He said, "ye think," because they would not obey, but merely prided themselves on the bare reading.

Then that they may not argue, "How, if we have not heard His voice, hath He testified unto thee?" He saith, "Search the Scriptures, for they are they which testify of Me." Since by these the Father gave His testimony. He gave it indeed by Jordan also and in the mount, but Christ bringeth not forward those voices; perhaps by doing so He would have been disbelieved; for one of them, that in the mount, they did not hear, and the other they heard indeed, but heeded not. For this reason He referreth them to the Scriptures, showing that from them cometh the Father's testimony, having first removed the old grounds on which they used to boast, either as having seen God or as having heard His voice. For as it was likely that they would disbelieve His voice, and picture to themselves what took place on Sinai, after first correcting their suspicions on these points, and showing that what had been done was a condescension, He then referreth them to the testimony of the Scriptures.

"Search the Scripture," saith He, "in which ye think ye have eternal life: the same bears witness of me; and ye will not come to me that ye may have life." Why do ye think that in the Scripture ye have eternal life? Ask itself to whom does it bear witness, and understand what is eternal life. And because for the sake of Moses they were willing to reject Christ, as an adversary to the ordinances and precepts of Moses, He convicts those same men as by another lamp.

For, indeed, all men are lamps, since they can be both lighted and extinguished. Moreover, when the lamps are wise, they shine and glow with the Spirit; yet also, if they did burn and are put out, they even stink. The servants of God remain good lamps by the oil of His mercy, not by their own strength. The free grace of God, truly, is the oil of the lamps. "For I have labored more than they all," saith a certain lamp; and lest he should seem to burn by his own strength, he added, "But not I, but the grace of God that was with me." All prophecy, therefore, before the coming of the Lord, is a lamp. Of this lamp the Apostle Peter says: "We have a more sure word of prophecy, to which ye do well giving heed, as unto a lamp shining in a dark place, until the day dawn, and the day-star arise in your hearts."

Or thus; they cannot have abiding in them the Word which was in the beginning, who came not to keep in mind, or fulfil in practice, that word of God which they hear. Having mentioned the testimonies of John, and the Father, and of His works, He adds now that of the Mosaic Law: Search the Scriptures, for in them ye think ye have eternal life; and they are they which testify of Me: as if He said, Ye think ye have eternal life in the Scriptures, and reject Me as being opposed to Moses: but you will find that Moses himself testifies to My being God, if you search the Scripture carefully. All Scripture indeed bears witness of Christ, whether by its types, or by prophets, or by the ministering of Angels. But the Jews did not believe these intimations of Christ, and therefore could not obtain eternal life: Ye will not come to Me, that ye may have life; meaning, The Scriptures bear witness of Me, but ye will not come to Me notwithstanding, i. e. ye will not believe on Me, and seek for salvation at My hands.
